I applied through Handshake from my university for GM's early career talent program. The entire interview process took ~1 month from start to end. The initial interview was a one-way behavioral interview done through HireVue. The questions were typical behavioral questions, you had 2-3minutes to answer each question and also had 2 attempts. About a week after finishing the behavioral assessment I received a 2-question coding challenge, 20 minutes for each question, which was through HireVue as well. The questions were standard leetcode easy questions. The questions required parsing standard input which I was unfamiliar with since I didn’t know my RegEx (Oops!). However, I wrote the code for the rest of the question and left a comment about how I didn’t know how to parse stdin for one of the questions and for the second question I was able to pass the tests. Surprisingly, I passed and received a request for a brief phone screen 9-10 days later with a current software developer. They asked basic questions about background stuff, career goals, and I received a request for a video interview 1-2 weeks later. The video interview was 2 hours overall, a 1 hour technical interview going through my resume and another hour with typical behavioral interview questions. I was extended an offer by phone a couple days later and had a week to accept the offer.
