It was nice, informative. One should prepare using all resources. They will judge your understanding based on everything that you ever demonstrated in the process, so be aware of everything you said or mentioned.

It was basically deep dive into resume and some questions on Dsa. The overall experience was good. There were 4 rounds in total. Be familiar with basics of the language that you primarily use.

3 rounds. 2 tech and 1 HR. The tech rounds lasted 1 hr 15 means each. HR was just formality for me though some had proper HR rounds. They wanna see how you work out solns with them over the actual one.
