I went through four interviews, a test and a presentation.
I first met their talent acquisition whom made sure both mine and their expectations aligned. I was then introduced to my immediate stakeholders, whom I could talk more technically with. At this point, I was given a test that I would later present. After the presentation, I was introduced to other management and HR, where the interviewing became more classical.
It was quite thorough, which also meant that I got a really good idea of what I was signing up and I felt like I was given a good chance to show my capabilities.
