First round with founder. Second with VP. 3rd with technical counterpart. 4th was a mix of a loop and presentation(data analysis), met with 8 individuals over 3 hours. A bit exhausting tbh. I was led to believe that some of the sessions on the 4th round would be informative and I would learn about the culture, etc but I was given more behavioral questions. 4th round felt like 4 interviews in itself.
