4 stages. The first one is the test. 20 questions, mostly underground maths and coding. The 2d interview is simple, just a call with someone in the company. More like get to know each other. They are keen on someone with robotics experience. I was rejected after that stage. They are very fast with decisions. I think I only waited a week or less after the application for the first stage and a couple of days between each stage.

I received an email about a month ago with a link to an online test. Please attempt it after practicing MCQs or revising linear algebra, data structures, and algorithms, as the test is quite difficult. After that, I had an initial call with the lead, who explained the interview process. He mentioned that there would be four to five rounds in total. The first stage was the live coding exam, which lasted an hour. The next stage would have been a paper discussion, involving reviewing and discussing a research topic. Unfortunately, I was only able to progress up to the coding exam, after which I was rejected.

The interview was 30 mins, including some technical questions, and a coding excerise. They asked me 2-3 questions first, then we started the coding excerise. The coding excerise was not difficult.
