First interview was a formal discussion with some technical questions which was perfect however the second interview involved solving gotcha-style exercises, live, in CorderPad. I had spent several days preparing to discuss advanced C++ topics but was instead required to reverse strings, count bits, and fix issues in code that no serious engineer would every write, and I struggled as a result. (I have since started doing LeetCode style exercises to be better prepared for this in future). When I asked for feedback after the interview process, so that I might improve, they ghosted me.
