The interview that I completed was an online HireVue recording. It took approximately 30mins and you only have one attempt to record. That means if you mess up, there are no second chances.
3 20-min interview super day. Seems like only the most senior interview matters. One VP, 2 analysts. No first round other than the hirevue. Took forever to hear back from HR.
The interview at GM was very difficult- requires a lot of preparation and memorization. Wouldn't recommend unless you're very well prepared. You should consult a current employee before applying for the job.
