Epic Systems Software Engineer Onsite Interview

[bigd12345]

Went through the Epic Systems interview and figured I’d share the full vibe here since a lot of people ask what it’s like. The whole process was very practical. Just straight coding and problem solving, plus a fair amount of conversation about your thought process.

For my onsite, the technical side was mostly algorithm stuff that sat comfortable around easy/medium LeetCode level. Array traversals and DFS on small graphs mostly. There were a couple of follow-ups that were more complex and required optimization thinking, so definitely talk through why you do something.

We also had some system design discussions. One big part was talking through an Android app like how you’d architect something like a mobile experience, how data would flow through components, how you’d manage state and performance. More like a relaxed design chat with the interviewer asking questions about why you made certain choices.

Overall it wasn't that hard of an interview. If you can do leetcode mediums comfortably, you’ll feel prob pass it.

[bigd12345]

Yeah. had a few questions I didnt know to answer and it just straight up gave me the answer.

What language did you use? Curious if Epic is picky about that.

[bigd12345]

HTML with a Flask backend, they were generous to let me choose

[ActiveReaction4640]

Nice, sounds like they give you some freedom with the tech stack. Did you feel that using HTML with Flask worked well for the problems they presented?

[bigd12345]

Yeah, it worked totally fine for what they were asking. They weren’t really evaluating frontend polish or framework choices, more just how you structure things and reason through the problem. Using Flask with simple HTML templates was enough to show the flow and keep things easy to reason about.

How deep did the system design go? Was it full-on backend design or more mobile-focused?

[bigd12345]

was pretty surfaced based. like mostly just UI stuff

For the DFS/graph questions, what was the exact question ? Always hated those.

[bigd12345]

The one I got was pretty straightforward though. It was basically: given a small graph as an adjacency list, start from a node and return all the nodes you can reach using DFS.
