Round: Technical Interview
Experience: This round involved solving two programming questions. Both the questions involved writing code on their editor, compiling it and running for few test cases provided by them.
Tips: 1) Make sure you practice writing more and more code during your preparation rather than passively reading/thinking of solution to coding questions
2) Make sure you 'think aloud' during the interview (discuss your approach/progress you have made regarding the question) even when you are stuck so that the interviewer can guide you to the correct direction. However, please don't confuse this with abruptly speaking of any solution that comes to you mind. Relax and take your time but don't hesitate to speak to the interviewer when stuck
3) Discuss the approach with the interviewer before proceeding to code your final solution
4) Write a readable code with proper variable naming, code reuse
5) Dry run your solution on few basic and corner test cases before flagging a question as done!
