It was behavioural mostly. They just look for a culture fit and how keen you are about their organization. As long as you're honest and exhibit curiosity you will do well. Karen is an absolute gem and provides such great mentorship. Leave a lasting impression by being keen and curious and you are bound to be called in with an offer. There was one other intern along with Karen since this was a coop opportunity. They spent a good chunk of the interview time answering my questions and elaborating on the process.
