Questions was on Robotics on which the interviewer has worked i.e., embedded. While I had worked on simulation and middle-ware in my previous projects.
A 5 hour exercise review safety components.
basic sorting, print prime numbers etc
asking ros, give me assignments
The last step looks like a system design interview but is a very high level conceptual system design. If you answer the interviewer's questions logically and have a good intellectual sound arguments then you should be good

I spent almost 1-hour answering the Technical Interviewer's questions on the introduction of myself, my dissertation, what skills I used in the dissertation, asking mechanical design problems that he was interested in my dissertation, and why I left my previous job. During 1 hour technical interview, he does not really ask me software questions. Most time he asked me about mechanical design questions. I non-stop answer his questions and almost lose my voice. I even do not have time to ask him relevant technical questions, but 1 hour is almost running out. It seems that the technical interviewer tries to learn from candidates but candidates do not have a chance to ask technical questions. After the interview, I got a rejection letter within the same day, saying my skills are not at the level that they require. I applied for a software engineer position. I assumed that they will ask me Python, Git version control, or ROS questions. But the technical Interviewer asked me mechanical questions. Then sent an email telling me that my skills are not at the level that they require. It does not make sense. Do they try to find someone to practice?! This totally wastes candidates' time. Since as candidates, we all spend time and do our best to prepare for interviews. Anyway, this is a super "interesting" company; be aware and careful.
Standard coding questions. General questions about C++ (shared pointers, containers) General questions about ROS (topics, services, actions)
