I applied through university. I interviewed at Epic in Sept 2019
Interview
First did a Rembrandt personality assessment, then a phone interview, both not too hard. Phone interview was not technical. I was asked about past projects, experience, why you picked your school. Then I did a skills assessment. This was long and difficult and administered through a testing service with a proctor who watched you through your webcam while you did the test. Has to be done all in one sitting and takes 3 hours. There were 3 sections. First section was timed and asked IQ test-like questions. Second section you were asked questions about a made-up programming language. Third section was 4 programming questions that started easy and got progressively more difficult. Received a rejection email pretty quickly, a few days after the assessment
Interview questions [4]
Question 1
Output the number of times each character appears in the input string in the order that they appear
Mingo problem: Given a 100x100 filled-out bingo board and a list of called numbers, determine if there was a bingo, and after how many calls the bingo occurred
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.
