ABB R&D Engineer Intern interview questions

HR called very quick talk got the main interview few days later. I did the interview online. It was focused on robotics programming so the questions they asked were related to matrix operations, programming fundamentals, and algorithms commonly seen in robotics(like A*). I think anyone who has taken linear algebra, basic programming, and DSA should be fine. Rest of interview was discussing my projects then discussing their project and how I can be helpful.
