First there was an initial HR screen, which, if it goes well, will be followed by a shorter meeting with the Hiring Manager. After this second interview, the final round interviews were structured such that I gave a 1 hour seminar to the department corresponding to the position and then had around 13 individual, half-hour long interviews with different people.

Multiple rounds with a lot of technical questions, and a very interactive team. The hiring team members were intelligent and respectful. It took some 3-4 weeks to complete all rounds. Enjoyed the interview process and was provided with feedback.
