I was contacted via email fairly quickly. I had one phone interview with a few behavioral questions and a super easy coding challenge before being brought out to Brooklyn. There were four brief interviews, half getting to know me and half simple coding challenges. It's unclear exactly how they can differentiate people off of those questions.

Applied online via their website. Was contacted the next day by a recruiter setting up a preliminary phone screen. A week later I spoke with an Engineering Manager for roughly ~30 minutes about my experience, why Etsy, etc... Nothing technical. The conversation was brief and easy. Then made it to the next round where I was invited for a day of interviews in their NY office. Unfortunately, I could not travel to Brooklyn due to distance. The recruiter said this was fine and scheduled 4 back-to-back Skype interviews, all with different team members. The first Skype interview lasted about 55 minutes and was merely culture-fit. We discussed technical challenges, life at Etsy, again, my experience, etc... About a week later I had the remaining 3 interviews back-to-back. The first two were technical, and lasted about 30 minutes. I was asked basic coding the questions, the first one being the easiest. The second interview was quite difficult and the interviewer didn't really say much/provide me with any guidance when I got stuck. The last interview was a 30 minute "walk-through" my resume, where an engineer asked me specific details about past internships and projects I've worked on.
