The application process started with an initial call from the person leading the team I'd be deployed in. There were some technical questions C++, but the chat was mostly about the work they do and guageing my experience. Then there was an HR interview to check my right to work status, salary expectations, etc. Finally, there was a whole day on-site interview where I was asked to prepare a 45min presentation on a problem/project I've been involved in, highlighting the problem and how I ended executing the project. This was followed by around 4 hours of technical interviews from the team and another HR interview. The technical interviews weren't overly complicated and the discussions were pleasant enough. Final verdict is that the on-site was quite long and exhausting, but I had a good time overall. Having to prepare a 45min presentation was a bit annoying through.
