First I was given a quick phone screening. They asked me about some projects I worked on and asked me what I liked to do in my free time. I was contacted the same day for an on-campus interview.
Before I went to the campus I have take a Personality profile test, and I had to compile all my transcripts from school as well find out what my old ACT scores were..
At Epic I had a full day of interview. You take three ACT-like test. One is 15 math questions, one is "learn-a-language" (I think it is MUMPS), and the final (and hardest) part is 3 programming questions. The programming questions are definitely what weed out candidates.
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.
