I applied through online, they contacted after 1 week through telephone. We had a short chat the HR behavior was good. They conducted online HR interview after two days. 1week later again I got an email and phone call asking a date for an online technical test. It was to test basic math, coding, and control theory. Unfortunately I did not make it well. I contacted them later, they replied by saying that my score is less. So did not go further.

They took 1 week to reach out. Then I had to do virtual interview and a hackerrank coding challenge. You could choose between C++, python, and Matlab. I choose matlab. The question were simple, they ranged from how to manipulate plots to loops.
