Microsoft Software Developer Internship interview questions

Applied after a recruiter reached out to me. Completed codility test (2 technical problems in 75 mins) and then had this first interview. The interviewer was great. He taught me a lot.

i applied through a person who works there and therefore got a quick response. first round was online coding skills test. it consisted of 2 tasks and time limit of 75 minutes. first task: given a string you must split into a minimal number of substrings in such a way that no letter occurs more than once in each substring. second task : 2 frogs that want to jump away and u need to return the longest distance
