R-Go Robotics interview questions

Started with a phone interview, in which I explained what I am looking for, and we discussed how I could fit several positions available at the time. Next, there was a technical interview which was challenging and reflects a real issue the company are trying to solve. The biggest concern I had is that the interviewer wanted me to apply for a different position that was more important for him to occupy, although I thought I had cleared up this issue on the phone interview. Feels like my time was wasted due to misunderstaning between the interviewers.
