Resonai interview questions

A short phone screening with HR, followed by an 0.5h zoom with a software developer (I assume team lead), where you are asked to solve a few leet code questions you are asked to answer using some online coding platform. it is not very standard start off an interview with a senior developer with leet code questions, and base the decision of wether or not the candidate fits the role based on his or her performance on these questions. I personally struggled with coming up with expected solution to the 2nd question which seems to have been the deciding factor in rejecting my candidacy
