Technical Behavioral
The interview process was pretty standard, involving three main stages: an initial call with the hiring manager for your future department, followed by a meeting with the head of the center, and finally, an interview with the head of the company or institute. While it might be basic for junior positions, it can get pretty intense for more senior ones, which is typical for a large corporation. A drawback is the significant waiting time for the final interview round and the background check, which can be very long.
