When accepted, you are suppose to sign up for both the phone interview (which was a great process and very informative) and the skills test.
My problem was with the skills test. You have to install software on your computer to prevent cheating rather than talking with a human at Epic. Then the test took like 4 hours to complete and is very exhausting and down right ridiculous at some points. Study up on simple trick questions you probably heard as a kid
Interview questions [1]
Question 1
Q: Two coins add up to fifteen cents, one of them is not a nickel. What are the coins?
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.
