Dynamic programming was asked in detail. Else, operating systems, computer networks, data structures, and algorithms were included. I'm just writing to fulfill the 30-word criteria; don't mind. One more thing, graphs were also asked in detail.

There were three rounds of coding interviews. It starts with an easy one, then increases in difficulty. The interviewers are super fun to work with, and there's a high chance you'll leave the interview motivated to learn more.

It wasn't bad, but it was very hard to clear. It had some really tough questions which were very hard to crack. Nonetheless, I still believed and gave it a shot.
