Wish Software Engineer interview questions

It was a hard process I got lucky on a lot of the questions. Mostly lest code medium / hard, the engineers were really great. Hiring manager was great got an offer 70k above asking

An initial phone call with HR, a programming challenge with an engineer in a remote environment. The HR phone call was ok. The programming challenge had problems that relates to binary trees and graphs. The question was not much difficult, but the interviewer's questions were hard to follow.
