I applied online. I interviewed at Epic in Jan 2018
Interview
The first step was a phone interview with a software developer in the company. They asked normal stuff like why you like coding, what projects have you made, how does the code in the projects work. After that, they take some time to explain what it’s like to work there. I actually didn’t think I did that well but I was contacted to schedule the technical phase a few days later.
In the technical phase, you take an online assessment while a proctor watches you through a webcam to make sure you aren’t cheating. There are 3 section. The first section is the only timed section and you answer as many math questions as you can within a couple minutes. In the second section, they give you specifications for a made up programming language and you answer questions. The third section has 4 programming questions. You could only use Java or C++ if you were applying to be a software developer. You are allowed scratch paper and a calculator. You can take a break between sections but not during. You can’t change tabs in your web browser or minimize the window. They let you know if they want you to go to an onsite interview within a couple weeks.
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.
