Technical+HR interview
I applied through college or university. The process took 1 day. I interviewed at National Instruments (Champaign, IL)
Interview
There were 2 behavioral questions and 2 coding questions. The two behavioral questions were a time I showed initiative and a time I had to debug something and how I approached it. The two coding questions covered how to represent data such as a deck of cards, and a question about traversing through trees. The interviewer was very friendly and made me feel at ease.
