Phone screening and then ~1 hour interview with the engineering manager. The engineering manager was rude, often interrupting or talking over me. It was really awkward and more like an interrogation than interview. I've actually never had such an unpleasant interview experience.
Their job listing is all over the place, tech wise and experience-required-wise. I would steer clear of them if you're an SE looking for a role right now. There are other companies that will treat you with respect.
