Epic interview questions

1 standard interview round, a very hard in test, then a second round consisting of panel interviews, a case study and a presentation. The second round takes up most of the day. The presentation is over anything you want, and the case study requires you to think very quick on your feet

Initial interview was 2 parts, one 30 minute phone call which was behavioral and about prior work experience. Second part was a 3 hour online assessment which asked you math and coding questions.
