One mental math test that lasts about 15 mins testing calculation skills and finding sequences and a hackerrank challenge that lasts 1h, need to answer 2 out of 3 questions using python/c++

Python interview, 3 leetcode mediums. Interview focused on linear data structures, no tree, graph, DP problems. Overall, not very hard. Was given 2 hours for the assessment. Had to be done in Python, so brush up on syntax if necessary.
