Applied through indeed and received a call within two days for an in person interview with the HR recruiter. Went to the interview on a Friday and recruiter said to come back for a second interview Monday. Second interview went well, I met with three people of different positions in the company and they asked questions about my professional life and a few scenario questions. Received a call within an hour after leaving the second interview to come for a third, this time with an HR director and associate director. Went to the third interview the following Wednesday and had similar questions as the second interview. Received another call to do a fourth interview. This time I was slightly confused as this was the first time I've ever gone beyond a third round interview with a company. I told them I wouldn't be able to make it in person due to my current job and they offered a Skype interview instead with the engineers which I really appreciated. Same question types with the engineers, scenario and professional mostly with a few personal questions about hobbies and interests. I asked them jokingly if there would be a fifth interview to which they said there most likely will be with the senior director. Got another Skype interview (5th) scheduled with the senior director who also asked about my hobbies and profession. Overall the process was slightly exhausting since my interview times were always during rush hours but very efficient, I did 5 interviews and got a job offer all within two weeks which is quite impressive. Make sure you're confident and know your resume inside and out and you'll be fine. I think they try to intimidate you by having multiple people interview you at once but everyone who interviewed me was pretty cool and friendly yet to the point.
