Clearpath Robotic Software Developer Engineer interview questions

I would say overall a waste of time, I passed take home programming & questionnaire. The latter was really time consuming with weird general questions. Then the technical interview, was ok, and then while I expect to hear some decision, they asked for another coding interview. This process was not really clear, neither were they so responsive. The coding interview was really stupid cause they focused on developing an old algorithm (RANSAC) which I didn't have any experience or knowledge! But they keep insisting on coding that! I would say for a start-up that is too much, come back to earth!
