H1 Senior Software Engineer interview questions

A telephonic Interview is taken and some basic questions are asked by the interviewer and explained about the company ended the call by saying that they will send a new meeting request for the next round but never came and after 25 days email came that I am not selected with no clear reason.

The overall process took 2 weeks. 1) A take home Hackerrank test. The test was medium to hard. It was 3 questions in 1.5 hours. 2) Coding interviews - medium to hard questions on Graph and DP Algos. 3) Past experience round - Deep dive into the past projects. Questions on the design choices involved, ambiguities faced along the way. Overall the interviewers were friendly and fun to talk to. Compared to other places I interviewed, the recruiters cared. They always responded promptly regarding any query.
