Applied online via their website.

Was contacted the next day by a recruiter, who set 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, I 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 four back-to-back Skype interviews, all with different team members.

The first Skype interview lasted about 55 minutes and was merely a culture fit. We discussed technical challenges, life at Etsy, and again, my experience.

About a week later, I had the remaining three interviews back-to-back.

• The first two were technical and lasted about 30 minutes. I was asked basic coding questions, the first one being the easiest.
• The second interview was quite difficult, and the interviewer didn't really say much or provide guidance when I got stuck.
• The last interview was a 30-minute "walk-through" of my resume, where an engineer asked me specific details about past internships and projects I've worked on.
