Epic Technical Problem-Solver interview questions

The interview consisted of three rounds: the first was a very laidback, behavioral interview in which the recruiter asked me about my future goals, passions and why I wanted to work at Epic. The second round was a GRE-Style Verbal and Math exam that was proctored online along with some very basic coding questions (a basic knowledge of data structures such as arrays should suffice). I was then invited to an on-site interview that involved a tour around campus. There was a case interview, a HR interview in which they asked questions such as if you had other offers how would you decide which offer to take. Then, there was a coding interview that I felt was relatively tough: knowledge of recursion, nested for-loops and more complex data structures was definitely necessary.
