I was part of three rounds of interview. The first round was a coding round which was very easy, consisted of a couple of MCQs and two codes. The second round was the virtual interview which was basics and fundamentals of robotics and path planning algorithms. Third round was a 48hr challenge which is a nightmare given the dependencies to manage in a legacy container. Even though I was able to do it (takes about 36-40hr). I got a call from the HR saying we won't be moving forward. Took them 18 days after 48hr challenge to revert.
