Epic Software Engineer interview questions

First round was a telephone interview, which is definitely not technical. They just ask about your experience and interest and few questions from your resume. Second was a programming assessment where you need to write program or algorithm for a given problem statement. It was total of 5 problems. Once cleared, then flew to Madison and had a one to one technical interview followed by a aptitude test and finally the HR interview.

Gave a phone interview which was nothing more than a walk through the resume. Then I was asked to give an assessment test which had 2 sections : Programming, A New language. The exam went well but I was rejected the next day without providing the reason. I am assuming it is because of the GPA. (Mine is below 3.5)
