Nimble Robotics Software Engineer interview questions

First it was a 72-hour hackathon, followed by a HR call. Then it was a techinical interview with a senior. There should be another techinical and another round with the CEO.

Way too many phone calls. At least 5 before I got to anyone with technical background. When I actually got some technical screen there was still no coding challenge or anything and I didn't get a callback. Wasn't sure what I messed up on. The next interview would have been with the CEO.
