I was interviewed before Nov 2020.

3 Interview Rounds

1

Telephonic Call Round (1 Question)

Round duration - 45 Minutes
Round difficulty - Easy

The interview started with a brief discussion of one of the projects mentioned in my resume, then the interviewer fast-forwarded to a coding problem. I was coding on a Google Doc which the interviewer was examining at the same time. The solution to the question involved knowledge of stack, and built-around logic definitely. I was able to solve this question but was asked to optimize it further. I couldn’t think about the optimization part before a small hint was given to me by the interviewer itself. I coded the additional optimization logic too as I could grasp the hint quickly.
In the end, the interviewer gave me the chance to ask him a question. And with this, the interview ended leaving me with no positive or negative feedback about my performance.
