I applied online. The process took 3 weeks. I interviewed at Epic in Apr 2014
Interview
First the will conduct a phone interview, which will be normal. No technical questions asked. It is a 1 hr interview probably with a developer, so as to see how you fit into their organisation. After that they will ask you to give an assessment test. This test is conducted only and is approx. 3 hrs. It includes all logical questions and some mathematical too. It is basically done to gather an understanding of how you think and what is your thought process. One of the part of the assessment is timed, rest are not.
If applying for a developer, you will also get 4 programming questions which you can do in any language. The questions are somewhat tricky and you will have to have a good understanding of programming concepts if you want to get through it.
If you clear this round, then they will call you for an onsite interview at there HQ. This is the time you will be able to have a good look at the company's workplace and their day to day life and environment. If you clear this round, then probably you will be getting an offer.
Good Luck for it!!
Interview questions [1]
Question 1
Programming questions test your in-depth knowledge
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.
