It is a long process if done during holidays however very simple and straight forward. You should review leetcode and STARS behavioral. It is multiple parts that being HireVue, Coding, phone call, and skype.
I applied online. The process took 2 weeks. I interviewed at General Motors (GM) (Phoenix, AZ) in Aug 2023
Interview
Online coding test was given by GM. Was given 70 minutes to complete two algorithms which were relatively easy. Finished within the time limit. Was later selected for more interviews that I have not yet completed.
Interview questions [1]
Question 1
I cannot remember exactly but they was an algorithm about solving a robot's movement pattern.
Not very difficult, most of the process was behavioral other than a coding assessment during the initial step. 3 rounds total that ended with a 1 hour video interview with one of the engineers on the team.
