Google Software Engineering Internship interview questions

Online tech interview submission that was based on a hash map leet code interview problem. I would say difficulty was around medium or hard. The interview was a solo interview that was emailed to my email.

First round involved standard medium level LeetCode question. Interviewer was nice, offered some tips and hints, and encouraged me to think aloud and brainstorm/go over the problem before starting. I was asked to write some unit tests to test my code worked.
