Expectation for coding Questions: Must be sort of analytical questions testing knowledge of DS/Algos and problem-solving skills, that could be done in 65-70 minutes. Reality: Problem Solving tricky questions, I would say they are not really checking candidate's Data Structures knowledge. Standard DS/Algos can be used to come up with the sol, but again coming up with the optimised sol. is the challenging part, I feel. I though it could only be done in the given time frame with most optimised approach, only if candidate had gone through that kind of question in the past. Brute Force or Semi-optimised approach can be thought of, but coming up with most optimised approach in the given time frame, needs some serious practice and some luck too😅. According to me, either questions' difficulty level should be reduced or time can be increased.
