Coding interview from Hackerrrank followed by a one-to-one interview about research experience and leadership principles. After that, there is another online interview focused on coding where you are supposed to code while other people interview you.
I interviewed at Amazon Robotics (Westborough, MA)
Interview
There are total 3-4 rounds depending on teams, roles and locations
The first round is on-screen coding (2 questions 70 minutes) and 20 minutes behavior. Then there is one on one coding round. Then technical round with senior research scientist.

Question 1
The technical round with research scientist. I was asked some research questions on diffusion policy, RL algorithms, adv and disadvantages of different types of action space in manipulation. How to go beyond data scaling? And few more questions on manipulation and mobile manipulation state of arm algo.
