The interview process was pretty straightforward. There were two back-to-back interviews.

I was a bit surprised by the first one's fast pace and messed it up. The second one was much better, but it didn't help. I was rejected by call and email.

The first interview focused mostly on small questions, like derived classes, binary search, and DFS. The second interview was much more complicated. Obviously, I could not finish it in 45 minutes, so the interviewer directly asked me to write only key functions. At last, we were still short of time, so pseudocode was also allowed. I'm pretty sure I did well in the second part.

Questions about derived classes, and binary search application using tree traversal. It took a bit of time to write the whole code, so the interviewer allowed me to write key functions instead.
