Most interviewers these days are like that. And some might be preparing and just want to make sure the candidate also prepared that much

Man I hate dsa based interviews but mazburi most corps ask that . I can solve those questions but at the time of the interview panic sweeps over ..

Most of the times these questions are copied from Leetcode or GFG

I once asked an interviewer if I could give him a question to solve and he panicked 🙂
