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.

Questions about both ROS and general software.
