1st stage was a phone interview with 3 senior engineers, mainly just to learn more about myself and ask questions on my CV. a few technical questions but nothing too difficult, more of how well you know about computers in general. 2nd stage was a face to face interview with 2 of the 3 same engineers as the phone interview. Went deeper into my CV as well as more challenging technical questions. Good experience, was quite nervous therefore struggled to articulate myself better.
