Phone screen, hackerrank assessment, 2 engineer interviews. The recruiter was good at hyping me up, it was a pleasant and fun conversation about the future of TuSimple and my possible role there. I had a technical mistake on my coding screen but they were willing to send me another. The coding screens arent too hard. I wasn't able to solve the challenge with one of their engineers in a 1 on 1 interview, but I got close I think. Overall the experience was very pleasant!
