Last year, I had a recruiter from Automattic reach out to me. Doing my research (as I always do), I read that the interview process is quite unusual. It might be different now, but at the time a candidate went through several interviews, two weeks of paid trial, more interviews, two weeks of waiting for an answer, and little feedback the whole time. So for me, that would mean at least a month of stress and unresolved anxiety. :) Lots of people on glassdoor describe the CEO as "mercurial."

But anyway, things I liked about the company are that they tend to work with mature technology stacks (e.g. probably a culture of iterative improvement vs teardown-and-rebuild) and that all engineers start out doing three weeks of helpdesk. That should be more common in the industry.
