Started with a screening, followed by an online timed coding challenge, a whiteboarding coding challenge with one of the engineers, and a conversation with the Director of Research. Felt fair overall.

Technical interview comprising Leetcode type C++ programming questions. The journey ended for me here, so I do not know what the rest of the process was like. They maintain the very popular robotic manipulation open-source framework MoveIt!, so there'll probably be a lot of projects to work on if you get in.
