This was the most difficult interview ever. I think the standard improved during this pandemic. I solved 75% of the questions but still failed.

The first round was a Hackerrank test, which was super easy.

The second round was a phone screen, a whiteboard interview on Coderpad. The questions themselves were easy, but the interviewers asked many questions in depth. These questions were all unrelated to daily work. If you prepared, you could pass; otherwise, you might fail.

HackerRank test. Hashmap. Smallest common element. Android knowledge. Android threading. Network.
