海外TECH	DEV Community	Problem Solving During Interviews For Anxious People	https://dev.to/maggiecodes_/problem-solving-during-interviews-for-anxious-people-2kpp	Problem Solving During Interviews For Anxious PeopleIt s important to note that I m not a mental health expert This is based on my personal experience If you re experiencing any serious mental health issues please reach out to someone you trust or a mental health expert immediately IntroductionUnfortunately the technical interviewing process for software developer jobs is deeply flawed According to a research study conducted by North Carolina State University and Microsoft white board technical interviews assess test anxiety rather than coding skills and resulted in women and minorities scoring worse I ve personally experienced anxiety during technical interviews that has negatively impacted my performance and led to many rejections In response to this I created a set of steps that I use to practice for technical interviews and then use during interviews Having a routine has immensely helped me perform much better during technical interviews Let s begin Problem Solving Routine BreatheFirst breathe Inhale exhale Breathe as many times as you need to Center yourself Believe in yourself You got this This step can be repeated as many times as necessary throughout the process Understand the ProblemIt s easy to jump right in and start coding right away However understanding the problem fully before coding can save you from wasting time later If you re taking a live interview ask questions Ask the interviewer to repeat the problem as needed You can even restate the problem to the interviewer to make sure you understand the problem before you start coding List the Problem RequirementsBefore you start coding gather the following pieces of information What s the program supposed to do What s the input and data type of the input What s the output and the data type of the output This will help you understand the problem identify any missing info and focus on the solution List Possible SolutionsDuring this step write down some possible solutions while speaking your thoughts out loud If you re in a live interview this will help the interviewer understand your thought process and they can provide further insight as they see fit If there s more than one solution choose the solution you re most comfortable coding even if it s not the most efficient solution or a brute force solution It s better to have a solution than none at all You can always optimize your solution in the end if there s time Test Your SolutionRun a few test cases Check if there are any edge cases or bugs Refactor as needed Optimize Your SolutionIf you have time look for ways to improve your solution This is where Big O notation comes into play SummaryIf you re someone who suffers from test anxiety know that you can succeed Having a problem solving routine may help you manage some of that anxiety during technical interviews as it has for me I hope my problem solving routine helps you in some way and feel free to change it to fit your needs	2020-10-04 21:07:42
