First, there was an interview on campus with a sales representative. Then, an all-day interview took place in Austin, TX at their headquarters, consisting of five 1:1 interviews and one 10-minute technical presentation. The presentation was given to 2-3 NI employees and 3-4 other competing candidates. The experience was enjoyable and the interviews were not stressful. They flew me out for the entire weekend, put me up in a really nice hotel for 3 nights, assigned to me a host who showed me around the whole weekend, took everyone to downtown Austin, went bar-hopping, and out to dinner.

They fly you to Austin and you meet with a bunch of different people to assess your personality, tech skills, people and presentation skills. Study basic programming interview questions about 200 level uni courses before you go.
