The whole process was super fast, except for the background check, which was handled by a third-party company. All the interviewers were putting in their effort to make it as fast as possible. All the interviewers had a positive attitude, and what I gathered is that they were positive because they were happy with their employer, so it just reflected to me during the interview sessions.

I don't exactly remember the question phrase itself, but it was trying to check if the person knows about rainbow attacks and the way to protect the system from it.
