Tableau Software interview questions

They did on-site interview for technical interview. I talked to the recruiter and he asked me question on linked lists, and then proceeded to sign me up for next day interview. After that, I met with the other recruiter to handle general information, then proceeded to meet up with one of the engineers for a technical interview.

I applied on-campus fair and got the next-day's on-campus interview. It's a technical interview for about 45 minutes. He introduced himself and then asked you to write code on the white board.
