I applied through a recruiter. The process took 2 weeks. I interviewed at Epic (Verona, WI) in Jan 2021
Interview
By far the most professional company I've interviewed for SWE positions. The recruiter was punctual, every interviewer and SWE I interacted with was extremely personable and nice. The interview process was structured and we had a good amount of time to get a feel for the company culture.
1st you get a phone screen and an Online Assessment. This step is where most people get rejected. Make sure to connect well with the interviewer. The online assessment is anonymously proctored. You will get asked 3-4 leetcode questions in addition to
Lastly you will have an 'onsite' interview. This may be onsite or remote depending on travel conditions. I can only speak to the online 'onsite'. This interview is a 4-5 hour interview. The first 3-4 hours is dedicated to learning about Epic's software, teams, and culture. The last hour is a technical interview, usually centered around a project.
Interview questions [1]
Question 1
Pills come in a variety of different sizes (eg 3mg, 5mg, 8mg)
Given an input amount of medication, design an API that returns the amount of pills of each type a patient needs to take such that the patient takes the minimum number of pills possible.
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.
