It was very smooth and super fast. They provide rapid evaluation. I really liked the process. The interview was very well structured and evaluated necessary skill set and coding ability.
I applied online. I interviewed at Epsilon (Chicago, IL) in Oct 2025
Interview
The interview process went well. First, I had the recruiter call, and after then, I moved on to the final round which lasted for about 1 hour with 3 members of the team on the call. They started off by asking me ML related questions and things I had done in my previous internship. After then, we moved on to the coding round (one LC easy and one SQL easy, which I did well within a few minutes). Since there was enough time remaining, they asked me some open ended questions, which I think I struggled with, but I think I did a good job with that. I waited for about a month to get a feedback, but was eventually rejected. I thought I did well, but looks like I didn't.

I applied online. The process took 3 weeks. I interviewed at Epsilon in Oct 2024
Interview
I was called for the final round of the interview which was for one hour and with two employees. Both of them were really cool but be prepared for 20-minute long live coding/DS questions and 20-minute long ML/Stats questions with a case study questions. Remember to think out loud and remember to brush up on hashmaps, time and space complexity, distributed programming, etc.
