From what the interviewer described, it's a general Interview (get-to-know-you), followed by a technical interview, a team-fit interview and then an interview with C-Levels. Went through the first, general interview and things seemed to go well. They gave me a take home technical assignment, which was pretty easy. Submitted it within a couple of days and emailed them. Didn't hear back from them for a week, so just sent another follow-up to make sure they received my assignment. Still no response, so I assumed I got rejected. Three weeks pass from the original interview and I finally get an email saying they want to setup the technical interview with less than 24 hours notice. Unfortunately, I say that I'm not available at the time they suggested, but I gave them free choice for ANY other time on ANY other day. Didn't hear back from them. Another 3 weeks pass and I receive a rejection letter. Overall, unresponsive and pretty unprofessional in my opinion.
