This was the least stressful interview process I've ever been a part of. The hiring manager was so nice and easygoing, and really only asked me about my prior experience and interest in the job.
I had a Zoom interview with the hiring manager and then moved on to an in-person interview at the Waltham campus with the hiring manager and three other members of the technical writing team. Again, it was all quite relaxed and focused on my experience and interest in the position.
