Advanced Intelligent Systems Robotics Software Engineer interview questions

it was over the zoom, with three main leaders. I had a presentation ready, I presented it for 20 minutes. They asked questions based on my presentation and my skill-set. They were looking for someone who is very professional in C++ programming, (which I didn't have enough experience). They were very kind, polite, professional people. They never sent an email whether they want to move forward or not. They kinda explained in the interview that I am not a good fit though. Although I did not get an offer, but it was a good experience.
