Leetcode like question with follow ups on c++ concepts like virtual memory, address space, etc. Coding everything from scratch and there’re also weird concepts like function pointer. Question was not too hard but need to remember concepts and syntax clearly

Did a set of interviews in summer 25. The interviews were not that difficult, mostly problems you'll face in real life. The interviewers themselves were mostly nice, although a couple seemed like they didn't care, not very involved in the process. Got rejected due to 2 sections having "mixed signals": one generic "not deep enough", the other didn't like the approach to solving a problem (it was solved on time anyway). Funnily enough, got praised for using the same approach in other section. Mixed signals also came from the people who wouldn't have been on the same team. It would be nice if interviewers were aligned on evaluation criteria, otherwise it becomes a guessing game. Other that that it was a positive experience and the rejection was delivered by phone, not a generic email.
