It took me 5 years to learn these 35 coding interview lessons. You can learn them in 5 minutes: 1) Most interviewers are on your side and want to see you perform well. 2) Prepare a short and concise introduction. 3) Be ready to discuss technical aspects of your projects in detail. 4) Understanding the problem well is the first step during interviews. 5) Never jump straight to the solution and start coding. 6) Ask clarifying questions about the problem and the constraints. 7) Never assume things which are not given in the problem. 8) Identify edge cases early on and design your solution accordingly. 9) Run through few input/output examples. 10) It’s ok to use pen and paper during the interview. 11) Pick a programming language you are most comfortable with. 12) Start simple, then optimize. 13) You are not expected to know the perfect solution immediately. 14) Ask for hints if stuck for long. 15) Listen attentively to the interviewer. 16) Discuss your approach before you begin coding. 17) Break down complex questions into small independent questions. 18) Prioritize optimizing repeated, overlapping, or redundant computations. 19) Avoid overcomplicating your solution. 20) Brainstorm which data structure is best suited for the problem. 21) Discuss the time and space complexity of your approach. 22) Start coding only when you're clear on what to write. 23) Don't just code, communicate. 24) Dry run few input/output examples to check for correctness. 25) Use meaningful variable names. 26) Write clean, readable and modular code. 27) Implement the core logic first and utility methods in the end. 28) Write tests to validate your solution. 29) Make sure your solution works for edge/boundary cases. 30) If time permits, refactor your code to make it more readable. 31) Behavioral questions are important too. 32) Have few questions to ask the interviewer. 33) Rest well before the interview. 34) Luck plays a significant role, so don't be disappointed if you aren't selected. 35) Use rejections as opportunities to identify areas for improvement. ♻️ Repost to help others in your network.
