I applied online. The process took 4 weeks. I interviewed at General Motors (GM) in Sep 2025
Interview
The interview process began with a phone screening conducted by a recruiter, where general questions were asked. Eric informed me that the process would involve six rounds, including multiple LeetCode-style interviews repeated across three rounds.
The first round was an online coding assessment on Codility, featuring LeetCode-style questions. The second round was another easy LeetCode-style problem, also conducted via Codility. In the third round, I spoke with a technical interviewer who focused on my past experience and asked questions related to Java, Kafka, and general backend development.
The fourth round was again LeetCode-style coding, and it was unclear why the same type of assessment was being repeated. The fifth round involved a system design interview.
The final round was a behavioral interview with Engineering Manager Hussain. Unfortunately, it didn’t feel like a meaningful conversation, as it seemed he was more interested in wrapping up the interview quickly.
I felt useless after going through a six-hour interview.

I interviewed at General Motors (GM) (Markham, ON)
Interview
The interview process focused primarily on C++ and object-oriented programming concepts, including both theoretical questions and practical problem-solving tasks. I was asked to demonstrate my understanding of core OOP principles, memory management, and real-world application design. The interview also included a technical task that allowed me to showcase my coding and reasoning skills. The process was well-structured and engaging. I was interviewed by two senior developers, and both were very professional and pleasant to interact with.

Interview
One of the worst interview process I’ve ever seen. Total of 6 rounds with an additional 7. 1st phase - phone screening with HR (which I had to reschedule because the hr wasn’t responsible enough to call me on the agreed time). 2nd phase - screening with some GM employee (it already feels like an full tech interview, in most of the companies this would be already enough). Then you’re finally approved for the 4 hour interview. Congrats.
4 hours, 4 different interviews, 3 technicals and 1 behavior. It was supposed to be 2 behaviors but the technical guys only asked me tech questions.
Behavior interview is not a big deal. Tech rounds took 1 hour, 15+ questions per round. Just. Insane.
In one of the tech interviews, the person was asking things so so specific, that only GM uses, and asking as it was the most basic thing ever. I’ve 15+ years of experience in automotive industry, in multiple competitors of GM, and I can tell that GM has the craziest recruitment process I’ve ever seen in my life. Lack of awareness, poor communication and feedback. And the salary is just average, we’re not talking about FAANG salaries. Don’t waste your time.
