I applied through college or university. The process took 3 weeks. I interviewed at Epic in Sep 2017
Interview
Met with a recruiter at a college career fair. They reached out to me for a phone interview and then an online proctored exam. The exam is estimated to take 2-3 hours which is exceptionally long. After the this, if they decide to move forward with you, they move on to an on-site interview. The skills assessment is both a behavioral questionnaire as well as programming in a text editor. You are unable to check syntax or compile your results so you're basically just winging it hopefully getting in the right direction. Overall, after having applied and interviewed with over 10 companies, this was probably the worst because of the 2 hour exam which ended up being a complete waste of time, as opposed to no other company requiring that long of a skills assessment.
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.
