Pretty much the same as what people said here except the onsite. Onsite is a terrible experience. Basically, one guy handling and controlling the entire interview process. Look at your resume, tried to pick a problem from it. My first hour during the tech interview, the guy was trying to ask me to turn a project on my resume which served as an online scheduling server into a school general service website. The next hour was working on a question, LeetCode 255. When I tried to code or start on something, he asked me to stop because my direction was not the same as the solution he had in hand. 2 hours passed.

Leetcode 255. Validate a tree traversal.
