Won't give away the problem, but I felt like it was kind of a mess. The email mentioned that it would be a problem solving exercise, so you should solve a few LCs/HRs to prepare. Valid tip, but the exercise was pretty far from doing a problem that you usually would with a tech company. I expected a collaborative session of me going through a problem and having the interviewer provide feedback in real. Instead, it really consisted of them copy and pasting a few problems and telling me they'd check up on me in a bit. My interviewer was also sharing their screen and I while working on my problem, their screen was still sharing so I could see them working on stuff. Kind of awkward TBH. I can't say the problems weren't fair, but I think it can be better executed. The length in which it requires to solve all their problems is in 1 hour, followed by the 0.5 hour discussion, really leaves no time to get comfortable and solve the actual problems fully.
