I got an email to do 2 coding challenges, you should study and do some leetcode to do these questions. Then a couple weeks after I was asked for the phone screening to schedule the two 1 hour interviews for the next week. He asked simple questions like why do you want to work at GM and basic questions like are you authorized to work here. 1 week later was the behavioral interviews which consisted of STAR questions with some technical questions here and there. The people interviewing me were really nice, and they were extremely easy to talk to. Make sure to study those STAR questions and to be yourself. Got a verbal offer 2 days after and a written offer the next week. Overall the process took 1 month.

After having my resume reviewed and completing my technical assessment, I was invited to a video call with two members of the hiring team, where I was asked a few questions.
