IGT interview questions

I applied online through a college website, and was contacted within a month to come in for an interview. I never heard back from them after reaching out after the interview.

A phone screen and an onsite panel interview. I had to dress up in a jacket and tie, the panel wore jeans and T-shirts which seemed odd. It was basically all their developers and managers sitting around a table (maybe 8) firing questions at me. There was one whiteboard coding quiz - identify all the elements in an array that appear multiple times and how many times they appear.
