Epsilon Interview Questions
& Process

The interview process had 4 rounds: technical, functional, and business. The final round was about 20 minutes, focused on my resignation reason (work-life balance) and my understanding of Epsilon. Surprisingly, no Business Analyst questions were asked, which was different from what HR had indicated. The interviewers seemed to have a fixed mindset, and the session felt unproductive and disappointing, especially after passing the first three rounds which were rigorous and relevant. This last round didn't seem to align with the role's expectations or the interview stage. It felt like an unfriendly environment, contrary to Epsilon's reputed employee-centric culture.

The interview process went pretty smoothly. Initially, I had a recruiter call. Following that, I advanced to the final round, which was an hour-long session with three team members. The interview began with machine learning questions and discussions about my past internship experiences. Then, we transitioned into a coding segment, which involved solving one easy LeetCode problem and one easy SQL problem, both of which I completed quickly. As there was still time left, I was asked some open-ended questions. I felt I didn't do my best on those, but overall, I think I performed adequately. It took about a month to receive feedback, and I was ultimately not selected. I thought I had done well, but it seems I didn't quite meet expectations.

The whole thing was a mess, way too long and disorganized, like they didn't care about anyone's time. It kicked off with 4 virtual interviews over like a month, with days in between each one. We did 2 technical ones, a manager one, and an HR one. Then, they called me in, I thought for salary stuff or an offer. Surprise! 2 more technical interviews back-to-back on-site, each pretty long, and they asked a bunch of the same questions again. After making me wait around forever, they basically said I wasn't a fit because of some 'very specific skill set' they couldn't even articulate properly. It's crazy, how did they not figure this out in the 5-6 interviews before? They asked about designing secure S3 access with Databricks tables, and I talked about row/column access, IAM, and S3 policies, but I guess not mentioning Unity Catalog right away was the deal-breaker, even though I'd worked with it. Honestly, expecting candidates to guess your exact internal design without any discussion is just bad judgment. It's a back-and-forth process, not a guessing game. Even after all that, I kept it professional. Then, 3 weeks later, the same HR calls me again, says the role is gone but there's a new one, and 'just one final round.' I agreed, but guess who it was? The same person from before! This time I nailed it, mentioned Unity Catalog and everything, but still, no feedback, no closure, just silence. To cap it off, a month later, another HR from Epsilon contacts me about a different job, totally clueless about my previous ordeal. When I declined, the HR got super rude and defensive, acting like I owed them something. They even started grilling me like 'Who was the HR? When did this happen?' and hung up. Clearly, Epsilon thinks candidates are disposable and interviews are just for their own amusement. No respect, no structure, just endless pointless rounds and ghosting.

The interview process kicked off with a 25-minute chat with a current employee, which was pretty relaxed. The final stage was a longer, 2.5-hour Zoom call with four Senior employees. HR started by talking about the role for about 30 minutes, and then I spoke with each of the four people for 30 minutes each. The questions asked were quite straightforward, nothing too complex. I was hoping for feedback as it was mentioned they would provide it, but unfortunately, none was given.
