I applied through a staffing agency. The process took 6 weeks. I interviewed at Epic in Aug 2012
Interview
I got an email from Epic stating that they would like to interview me. I had a 30 min phone interview asking generic questions (why would you like to work here, what qualifications do you have, etc.). Once that was done, I got an email stating that they would like a writing sample from me. I had 60 minutes to complete it. It had to be at least 300 words. I had to write an autobiography of me as if it were to appear in the New York Times. After I submitted that, I had to take an assessment exam at a testing center. There were two parts to it. One was simple math questions. The other part was logic questions.
Interview questions [1]
Question 1
Writing an autobiography about me in 300-600 words in 60 minutes.
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.
