Problem : ------------- Use a Map data structure to implement enqueue and dequeue operations. My approach : ------------------- I clearly laid out the assumptions, options/solutions along with time & space complexity and pros & cons , explained the algorithm and finally coded & executed it successfully with the given time. Experience and observations: -------------------------------------- The interviewer was a software engineer and sounded more like a fresher. His focus was more on the API's , specifically method signatures. The web version of coderpad wasn't an intelligent editor, so ran into 9 syntax errors because of a missing closing bracket. The interviewer was so panicked and I asked him to calm down. The compiler logs clearly indicated the line number and reason as well, I went and fixed it and successfully completed my exercise. Unfortunately that is the problem with freshers interviewing experienced people, they have limited understanding about the process (what to ask, look, expect for and when & when not to panic). That isn't their fault but their program/recruitment process must have trained them on how to conduct and what to expect from an interview. Recommendation: -------------------------- 1. Interview panel should consider of a mix of experienced and freshers with diverse thinking. This is one the worst things startups do and then learn over a period of time. 2. Train your employees on how to conduct interviews.(what to ask & what to expect)
