海外TECH	DEV Community	How I Got Hired at Amazon	https://dev.to/bytebodger/how-i-got-hired-at-amazon-3ajl	How I Got Hired at AmazonSo I got hired at Amazon I wanted to write this post because my previous posts may have given the impression that I have some kinda axe to grind with Big Tech and I know that many people genuinely wonder How do I get into one of those big companies So this is my story By the way if you wanna hear about my previous experience getting rejected by Facebook you can read about that here Buyer BewareFirst I wanna make it clear that this is not a How To article I didn t write this to simply list out Here s what I was asked and here are the correct answers My process may not map to your process when if you apply But I did learn a few things that may be helpful to you if you re trying to get onboard with a FAANG company Second this article is not some kinda humble brag You re not a better dev because you work for Big Tech Some of the best devs I ve ever met have never worked for a FAANG company That being said Big Tech typically pays Big Money And even if money were no issue a lotta devs would love to have that chit on their resume that says they worked for a FAANG company So I m just gonna share the lessons that I learned in the process Your mileage may vary Lesson Big Tech Companies Are Not MonolithsWhat do I mean by this Well I ve been pinged by Amazon recruiters on and off for the last coupla years During a few of those interactions it was clear that the potential role was either onsite at an Amazon location or would only be remote until COVID blew over For all of those opportunities I politely declined Many Different OpportunitiesBut a company like Amazon has more than a million employees on hundreds of teams So just because this opportunity is for onsite only work or any other restrictive condition doesn t mean that all of their opportunities have the same restrictions Also the hiring process is not identical for every role or every team Sure an established company like Amazon will have certain HR guidelines that they probably need to follow for every interview but that doesn t mean that the process required to be hired as a database engineer for a team based out of Seattle will be identical to the process required to be hired as a frontend dev for a team based out of Phoenix AssessmentsSpecifically during my first several interactions with Amazon recruiters I was sent instructions to first complete an online assessment And while I m not necessarily opposed to the idea of doing an online assessment I ve written extensively about what is as I perceive it to be the myriad of BS hurdles that are presented by these assessments In fact the very first article I ever wrote for Dev to was about the folly of coding tests You can read it here During previous interactions I was simply too bogged down with my current job to consider taking these assessments I went to the assessment site and even took some of the sample tests But I quickly realized that they were gonna ask me about a ton of esoteric concepts that I simply couldn t be bothered to study up on before I took the tests So I simply did not take the tests and I allowed those opportunities to fall by the wayside This go around was a little different from my perspective First I was basically between gigs so I was more open to idea that I might have to trudge through their assessements But second I also found much to my delight that this current opportunity did not require me to do an upfront online assessment at all If At First You Don t Succeed You should also keep in mind that even if you completely bomb your interview process you can always apply again at some point in the future FWIW I believe the policy at Amazon allows you to re apply every six months Granted I m sure that your past results will still be recorded somewhere in their system And you probably don t want to apply willy nilly if your skills aren t up to snuff because you won t want those abject failures to be sitting in your permanent record to be perused by the next Amazon hiring manager the next time that you apply But re applying to a massive company like Amazon is not the same as re applying to some small dev shop in your local town Once you ve been eliminated by a small local company there s a reasonable argument to be made that maybe you needn t bother applying to them again anytime soon especially if the hiring managers who rejected you last year are still in place this year But companies like Amazon are so friggin massive that a completely different team next year may love you even if the team you interviewed with this year found you to be unqualified Lesson Take NotesAmazon s interview process is loooooong And that may sound rather daunting But there s a silver lining to all those interviews Specifically you may find that something told to you in an earlier interview will help you do better in a later interview Pay AttentionFor example I was told in only my second interview that in a later interview they d probably ask me about the Amazon Leadership Principles and that I should be prepared to answer such a question So what did I do I acted like a complete idiot You see it took them quite a while weeks to set up all the interviews Initially I read through Amazon s Leadership Principles and I was prepared to talk about them But by the time they got my later interviews scheduled I had spent weeks boning up on all sortsa technical details and I completely forgot to re acquaint myself with the Leadership Principles So in one of my last interviews the interviewer asked me Which of Amazon s Leadership Principles is most important to you and why Of course as soon as she dropped this question on me I thought Awww crap Be Honest About What You Don t KnowHow did I disguise this faux pas on my part I didn t I just told her straight up that I did read the principles several weeks earlier and I even had an answer to that question a while ago but that I d forgotten to re read them before this interview did not have them in front of me and could not recall them from memory Was this the smoothest course of action Probably not But I m sure my dead honest answer was better than trying to make up something on the fly And thankfully it didn t keep them from extending me an offer Lesson Focus On Core JavaScriptObviously this lesson is most applicable to those applying for frontend or Node centric roles On the surface this probably sounds obvious After all whether you re a wizard with jQuery Angular React Vue Svelte Node or any other popular framework it s all just JavaScript So if you claim to know these things you d hopefully be extremely comfortable with plain ol JavaScript right But here are the reasons why I list this as a core lesson I was actually mildly surprised at how many of the coding tasks focused on nothing more than plain ol JavaScript even though I was being interviewed for a role that would presumably be anchored in React I did end up talking about React concepts during some of my interviews But every coding task given to me was to be written in plain ol JavaScript This created a small problem for me when in one of the interviews as it turns out this interview was with my future manager I was asked to code up some basic DOM manipulation features To be clear I completed the task But if I m being honest I was thrown for a little bit of a loop as I first thought about how to code the solution because for the last years I ve been writing soooooo much React specific code that I had to stop and think for a minute about the best way to solve the problem without using those same React specific features or features of any other common framework for that matter One additional note here I don t actually know that I couldn t have coded my solutions in React Granted the coding window presented to me was labeled as being simply JavaScript And the default expectation from the interviewers was certainly that I d be writing solutions in plain ol JavaScript But we weren t running the code in their platform anyway more about that in the next lesson And many of my interviewers were very familiar with React So in hindsight I m not actually certain whether it would ve been a problem if I d simply started cranking out code in React Lesson Keep A Local Terminal Or Browser Open During InterviewsWhen you interview with Amazon they will invite you to do coding solutions in their own shared in house tool This tool is not unlike many of the other online portals you ve seen where you can write some test JavaScript in a browser window e g StackBlitz or JSFiddle or CodeSandbox However there was one aspect of their tool that threw me for a bit of a loop You can t run your JavaScript in their online interviewing coding portal Here s why that was a small problem for me Just Run The CodeAt one point one of the interviewers asked me to code up a JavaScript function that would recursively build an object based on a period delimited string I proceeded to write my solution even talking through each aspect as I typed it out When I was finished the interviewer pointed out to me that my solution was very close but that it had a small flaw in it Here s the funny part As soon as he pointed out my mistake I could immediately see that he was right It was clear to me that I had to make some kinda change to finish the task But I was having a bit of a problem simply thinking in my mind about how I needed to tweak the code to solve the problem This stalled me for a minute because in my previous jobs while pouring through thousands of lines of code it s typically impractical to expect anyone to run the code entirely in their mind Granted I can often spot problems simply by reading code my code or anyone else s but when I m pretty certain that a problem exists I pull the code up on my localhost and then I proceed to play with it until the problem s fixed Run The Code Wherever You CanTypically this takes very little time Once I can run the problematic code I can usually narrow the problem down quite efficiently That s because rather than just trying to stare at the code and think about why it s not correct I simply run the code When I m running the code I just start dropping breakpoints or console log s into the code And then once I m running the problematic code and inspecting the variables in real time it s usually dead obvious what needs to be tweaked to make it meet the spec In retrospect it didn t have to be this way To be clear they never even hinted that I couldn t have other windows open during the interview process In fact in several of the interviews I announced to them that I was simply gonna grab some of my pre existing code to illustrate a given concept And they never complained about this at all So I now realize that there probably wouldn t have been any problem if I d simply copied n pasted the problematic code into another window where I could run it inspected a few of the variables made any necessary tweaks and then copied n pasted the improved solution back into Amazon s code sharing tool Lesson Don t Be Afraid To Paste Anything Important Into Their Coding ToolFirst understand that anything you write in Amazon s coding interviewing tool will be saved In other words all of the other interviewers will be able to see anything that you coded while talking to this interviewer Presumably they will take all of that into account as they make their recommendations This wasn t entirely clear to me until one of my last interviews We were going through concepts of API asynchronous calls and I spent copious amounts of time basically trying to re code stuff that I ve long ago solved in my other apps I did this because I just assumed that I had to type everything in the Amazon coding window from scratch Put Supporting Evidence In The Coding WindowI completed the task and my solution worked but it was definitely much more bare than anything I d typically put in production So I told the interviewer This is how I usually address this task Then I proceeded to copy n paste my standard solution out of one of my GitHub repos and into the coding window When I did this the interviewer made a point of adding comments directly above my copied n pasted code basically indicating to any of the other interviewers that this was my more complete solution pasted from another of my apps and that they should take the time to review it Quite frankly there were numerous coding tasks for which I could ve provided a more holistic solution if I hadn t already burdened myself with the preconceived notion that I had to type out everything from scratch in their custom portal as they watched So if you already have some solid code that illustrates the concept they re asking you to write don t be shy about doing some quick copying n pasting during the interview Lesson Be Prepared To Spend A Lotta Time In The ProcessThis probably goes without saying but Big Tech companies can afford to conduct a long interview process And they ll probably schedule it at their leisure All told I had seven interviews with Amazon The first was the cursory screening call with their internal recruiter The second was a technical call but it was basically a screen to ensure that I was worthy of the full process Once I passed the technical screening they then proceeded to schedule the remaining five interviews They will try to schedule all five of those final interviews in the same day But due to scheduling conflicts with the evaluators my last five interviews ended up taking place over the course of two days It also took them nearly three weeks to get all of those last five interviews lined up and confirmed Overall my interviewees were in the following roles The internal Amazon recruiterA technical screener who was pretty senior and knowledgeable in his own right but doesn t really get a chance to touch the code much anymoreA backend Node API engineerA senior frontend engineerThe dev manager for the team doing the hiringA BA PM typeA senior architectI was expected to code during interviews and After the initial recruiter screening every other interview was scheduled for exactly one hour And to their credit they were very fastidious about keeping to that time constraint Lesson Talk And Code But Don t Argue I was asked to do live coding in five of the seven interviews So if you have any problems cranking out some code while someone s looking virtually over your shoulder you ll definitely need to get over that Quite frankly I m quite certain that there s just no way around this You re gonna have to code in a real time environment and you re gonna have to do it while an interviewer is watching you My best suggestion here is to talk through your solutions They didn t require that I do this But I know from a ton of experience both in hiring and in applying that even minor coding challenges can start to eat away at your psyche if you re just staring at the screen in silence as you try to formulate all of the code in your mind Use Your Words To Demonstrate Your KnowledgeFor me at least talking through the process not only helps me to organize my thoughts and my code as I m completing the exercise but it also illustrates to the interviewer that I m not just mashing the keyboard in a desperate attempt to come up with a solution In other words what you say can be just as vital to demonstrating your knowledge as what you type Talking through your solutions can have an additional benefit as well When you talk through the problem and perhaps even talk through the code that you re writing onscreen you may be surprised at just how much the interviewer actively nudges you along If you sit there in utter silence slowly cranking out a few lines of code as you grasp for an answer the interviewer will quickly get the feeling that you may be in over your head But when you talk through the solution the interviewer can hopefully recognize that you pretty much know how to solve the problem and any continuing delay is just caused by you futzing over an exact solution And once the interviewer feels confident that you actually understand the problem and that you legitimately know how to code they can often be much more helpful in guiding you to the exact lines of code that are required to complete the exercise I was also surprised at just how much of each interview was occupied merely by talking In each of the five coding interviews every single interviewer used almost half of the time to merely ask me coding questions In fact I think there was one where we didn t even open up the coding window until we had only minutes left in the interview Discuss But Don t ArgueMy only caveat here is that while you should be prepared to talk through many technical concepts you definitely shouldn t get dragged into arguing about any of them And obviously that little bit of sage wisdom probably applies to any interview with any company In my third technical interview I was talking with a frontend engineer And it became immediately apparent that he and I shared many coding philosophies Specifically I alluded to fact that I m not a big fan of TypeScript or Redux He was chuckling and nodding along As you can imagine that interview went quite well In my last interview I was talking with a senior architect And he was absolutely a huge proponent of both TypeScript and Redux Did that present any real problem for me No In fact we had a good discussion about both technologies and I believe I was very clear that I appreciate them both as tools that should essentially be used when they are the right tool for the job Granted I think he and I disagreed on what some of those exact purposes were but I definitely don t believe that my contradictory opinions on TS Redux were any impediment to my receiving an offer Lesson No Gotcha QuestionsOK maybe this isn t a lesson that applies to all Big Tech interviews It may not even apply to all Amazon interviews But when the whole process was finished I was actually incredibly surprised to realize that I was never asked a single question that I would classify as a Gotcha question Google s famous for their thought experiment questions I was already given a heads up about some of the Gotcha questions I might be asked by Facebook But through seven separate Amazon interviews I was never asked a single question that I considered to be obtuse or esoteric Quite frankly this shocked me In fact I thought many of the questions tasks were pretty basic To be clear just because a question has a basic answer doesn t mean that you can t use the opportunity to expound upon the response and demonstrate deeper knowledge But I didn t get any of those kindsa questions that tend to piss off even senior devs You know what I m talking about They blow the answer and then after the interview they hit up all their dev buddies and say Can you believe that they actually asked me about INSERT SELDOM USED ESOTERIC CONCEPT HERE I was also surprised by how few of the conversations were bloated with talk of academic concepts During my second interview the tech screening we talked very briefly about Big O But we never delved too deeply into it And he didn t seem to care less that I couldn t recite from memory the Big O complexity of a Shell Sort No one asked me to code a binary tree search No one expected me to have all the vagaries of Regex immediately available from memory No one asked me for the default th parameter value of Array prototype reduceRight First Day At AmazonI m publishing this post on my first day of work at Amazon No I won t be working on a fulfilment line But I thought the above pic felt more like Amazon employees than just showing nerds like me sitting in front of a computer screen Is it easy to get a coding job at Amazon or any other Big Tech company No I definitely don t think so But if you re read what I wrote under Lesson you ll see that I basically self eliminated myself several times in the last few years To be perfectly frank the process felt onerous and I really didn t want to go through it But now that I ve been through the process it really doesn t feel anywhere near as onerous as I d imagined it to be Of course I give you absolutely no guarantees that your experience will in any way mirror mine There are interviewers out there at nearly every company who will try to sabotage you with litmus tests and Gotcha questions Every large company has at least some Grade A buttholes who think it s clever to ask you about arcane quirks in a given programming language Maybe Amazon is one of those companies on the whole and I just got lucky this time Who knows In case it s not already obvious I m not claiming that a Big Tech job is the right path for anyone else out there Working for a tech giant can have some unique challenges to be sure Hell I don t even know whether it will be a good fit for me But I m honestly pretty excited to explore this new Big Tech path for all it s worth And if it all ends badly I ll just turn it into
