I handed out my resume at my university's career fair and I got a call back from a NI rep who was at the fair the same day and we scheduled a 1:1 for the next morning. The questions were pretty standard tell me about a time things didn't go well... tell me about a time when you went above and beyond... when have you been challenged? etc... Then the technical part was a series of questions having you to do some things with a deck of cards (shuffling, drawing, etc...) There were some serious issues with being contacted about whether or not I would be offered a job though. I was supposed hear yes or no after 2 weeks but it ended up taking a month and a half (with a lot of "am I still being considered?" emails to keep things moving).
