There were 5 separate interviews with the different levels of the company employees, your future teammates and managers. Most of the questions were intent to check how good the future employee would fit the company's values

Had the initial HR screening and then 9 full individual rounds of interviewing followed. There's a technical assessment which wasn't very challenging, however the presentation to a panel was something else. One member of the team specifically was being very difficult, asking questions that were off topic to what was being presented. I answered his questions anyway with real examples from my ten years of experience in the field, but apparently my answers were the reason they didn't hire me. Which I found out after 5 more rounds of interviews. Dodged a bullet big time as that person would have been my manager. Long drawn out process, salary was considerably lower than where I ended up, but they acted like this was the top tech company in the world to work for.
