I applied through university. The process took 3 weeks. I interviewed at Epic
Interview
1st thing is a phone call with an engineer, mostly to gauge your own interest. They will ask you a simple coding question, you only need to give a high level walkthrough of your approach. Next is the famed ProctorU assessment. I got lucky and my proctor left me alone but YMMV. I've heard of some people getting their test paused because they looked at a wall. The code questions were 1 leetcode easy, 1 leetcode easy-medium, and 2 mediums. Not too bad overall if you've done your prep, overall slightly easier than some company's code interviews, if I were to rank, maybe a bit more difficult than Amazon's. Took me 2.5 hours. Can't run your code, but they're also not expecting 100% correct. I think pseudocode is ok. My solution was correct, but not 100% optimal, so there's leeway here. The onsite is super easy, mostly presentations/discussion. I talked with a developer about my prior internship project, had a quick discussion about how I would design something, and a final HR interview mostly discussing deadlines and that sort of thing. Very relaxed onsite, and the whole process was extremely smooth. They take very good care of you.
Interview questions [1]
Question 1
Something about well ordered numbers and additive sequences. They have a hard on for recursion.
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.
