First-round itself was a technical interview. The topics were Mathematics ( calculus, matrices, and probability), Control systems (including signal processing fundamentals), MATLAB, and C programming. It was an online interview where the interview website has a chatbox and whiteboard. The candidate has to solve typical questions on white board and should reply to the interviewer via whiteboard.

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
