The phone screen was within 2 weeks of application. First round of in-person interviews with 5 people was around 2 weeks from the phone screen. 2nd round of in-person interviews with 5 more people were 3 months later, which was scheduled after I reached out to ask about status. Then, I was called with feedback on why I didn't get the role, which was before they had finished that round with other candidates. Even factoring in the size of the company, there are many people to do work that is done by fewer people in other companies, so the specifics of the job requirement are quite detailed. Being a highly desirable company and well-resourced, they can afford to find someone very specific and take their time.
