I applied online through their Careers page, and was contacted by an HR rep a few days later to have a phone screen in early November. They just asked about my professional experience and my resume, and it went well enough that they wanted me to come in for an on-site, about 2 weeks later. The on-site interview was 3.5 hours long, and consisted of 4 rounds of interviews, one 2:1 and three 1:1's. In the first round, two of their engineers asked me a few technical questions regarding what occurs with respect to the program stack when a function is called, and then they had me solve 2 LeetCode Easy problems (listed below; they literally had me work these problems on the LeetCode website using one of their laptops). I was able to get through the first LeetCode problem fairly quickly, but I only had 10 mins to try and solve the second one, so I wasn't able to finish it in time. The next rounds were a lot less technical, and were primarily questions on whether or not I had experience with a certain tool or framework, such as AUTOSAR. One round was primarily behavioral questions on how I'd react in certain situations. They also gave me a short tour through the Irvine facility, which looked like a massive version of an automotive lab you could find at a university; I was honestly really impressed with the work environment. Overall, I felt fairly good about how I performed during the interview, but unfortunately they did not extend an offer to me, and sent me a rejection email 2 days after my on-site visit. However, my experience with them was pretty positive, and so I'd be happy to interview with them again in the future.
