The interview process was actually pretty fast. The recruiter called to schedule three independent interviews:

1. A technical interview with the team lead.
2. A design interview with one of the senior engineers on the team.
3. A technical interview with the group manager.

All interviews were remote, and the interviewers were nice and really tried to make me feel comfortable.

Each interview also included some behavioral and culture questions.

After I passed those three interviews, the recruiter scheduled the AA interview. This was purely a behavioral interview to check if I was a good fit for the company.

A few days after the AA interview, I got a call to inform me that they were working on an offer for me. I heard this interview can include some technical questions as well.

I'm not sure they would appreciate me describing the questions.

But they were in C++ to implement some mechanisms that include concurrency programming.

There was a design question: pretty simple, to see how I would design a system that needs to be handled with locks and priorities.

Another C++ implementation question was to implement some objects that are already part of C++.
