Protonshub Technologies Associate Software Engineer interview questions

I was giving an online assessment which contained 15 mcq questions and 2 coding questions. The mcq questions focused on core computer science concepts such as DBMS, OOPS, OS, CN and Java. ample time of 2 min for each mcq was given and I was satisfied with the level of questions but then I saw the coding questions and the time was highly insuffiecient to solve them. 1st question was from dynamic programming and only 10 min were given for that question and the 2nd question was about monotonic stack and only 5 min were given to solve that question, this is highly insuffiecient and no one can solve such questions in the given amount of time.

The interview process is of 3 rounds in round one there is a OA in which you have 15 mcq and 3 coding questions for coding questions you have very less time and others are still remaining for me
