After the initial resume screening, there is a hackerrank round which in my case had three questions building on gradually. After this, there is a Karat virtual interview, which lasts around 1h. The first 10-15 minute is spent on some algorithmic questions, mostly about time complexity about some programs. Then the following 45 minute is spent on coding questions. It's one of those "do as much as you can within the time limit" interviews. I got 2 correct, and the third one passed all but one test cases. I got a call for the next round.
