Applied online and all interviews occurred remotely. Heard from the HR recruiter within a week where he scheduled the first interview which was the standard HR kind of thing. Went well. Second interview was a week later with a lead engineer who asked me to rate my competencies in various technical areas and focused the questions on those competencies. That also went well and I was scheduled for a third interview The third interview was the most rigorous. It involved screen sharing and coding online. There were three questions. The first one was a fairly straightforward coding exercise in Java, the second was an extension of the first one and was much more difficult and the third was a verbal discussion where I was asked to design a using OOP. The first two questions were drawn from actual problems they had to solve which I thought was very cool (vice something textbook or a made up exercise). Everyone was very nice and professional. That gave me a really good feeling about Epsilon and I got the call from the recruiter about a week later and we discussed the details of the offer that I accepted.
