I applied online. The process took 6 weeks. I interviewed at Epic in Oct 2014
Interview
Submit an application. 30 min phone interview that was half behavioral/half tech. 2-3 hour online logic, math and programming test. First three sections were fairly simple but the last coding section was pretty difficult. After that they offered me an onsite interview. Interview 'superday' started with a software demo, then a chat with a developer. Tech interview, lunch, tour of the amazing campus, and finished with an HR interview.
Interview questions [1]
Question 1
The most difficult part was just walking through a past project and explaining thought process and how to improve the code.
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.
