First round was an online interview with department head and HR. Second round was a psych eval and psych/IQ test. Third/fourth round was a Python test and a talk with the team head and HR. Fourth was an offer. I would like to add that I didn't know Python and didn't take the test at first. Later I learned it and contacted dSpace about it. They messaged me at first job opening and then I took the test. Very accommodating and everything/everyone was extremely pleasant.
