I applied online. I interviewed at Epic (Verona, WI) in Feb 2021
Interview
Interview started with a quick recruiter call to discuss my background, experience, and interest in Epic. Answered any questions I had about the position and work at the company.
Next round was a proctored online technical exam, expect at least 3-4 hours in length. Consisted of 3 rounds, one extremely quick round of logic / math questions. Next round was answering questions about a fictional programming language, then finally a few programming questions without the aid of a compiler. Proctor was a bit difficult and would harass me about looking off to the side (was just thinking).
Final round was a presentation about Epic's software with several other interviewees, a group QA session, an easy system design round, then a final discussion with a recruiter. Have good questions prepared and be social, the onsite is mostly a personality test.
After I received the offer I was given the option to tour Epic's campus, which I did. It's a nice location but gave off the impression of being a stressed-out corporate Disneyland.
Recruiter was extremely helpful and transparent, guided me throughout the entire process. Patient and gave me plenty of time to make a decision on the offer.
Interview questions [1]
Question 1
Answer questions about a fictional programming language.
Find the angle between the hands in a clock.
Longest chain of numbers that add together given string.
Design a system to call patients regarding scheduled immunizations.
Medium level leetcode and then a very basic system design question as a final round interview. Overall, smooth and simple process. Only one technical and it was the first one.
Interview questions [1]
Question 1
How would you design a system to minimize wait time at a health care center?
First round is a thirty minute phone call with one of their developers. The other part of the first round is a three hour exam with IQ test style logic questions and coding questions.
[OA] OA was fair. Programming part are leetcode easy and easy-mediums, straightforward simulation, backtracking, dfs, strings, etc. No DP/graphs but ymmv.
[Final interview] (Case Study) I think the interviewer came up with their own prompt. It's mostly discussion-based, with a virtual white board. It's not too technical. I'm guessing its testing your communication/logical reasoning than system design skills. (Pair programming) 1 question, same format as the OA on the same platform, leetcode easy.
[Overall] Technical difficulty isn't bad. Interviewers who are current software devs seemed friendly. Had a good experience, yet got rejected.
