I was invited to my first on-campus interview the day after talking to Target at the career fair at my college which consisted of behavioral questions followed by a hackerrank assignment of about 7-8 questions. Headquarter interview was a full day interview which consisted of an Info session, then broke up into interviews (2 x30min w/ break in-between) with lead engineers (questions are depend on your interviewer) , lunch QA panel with current TLP members, tour of HQ, and tour of Minneapolis. No algorithm sort of questions. More behavioral and technical oriented questions.

Three rounds of interviews - recruiter, second round, and final round. The recruiter call was 15 minutes over the phone and went well. The second round was two thirty minute interviews with both technical and behavioral questions. The final round was three hours and included a company presentation, informational one on one session with current employee and two thirty and fourth five minute interviews with both technical and behavioral questions from current employees.
