Applied through university job posting portal. Then a phone interview with HR Recruiter that lasted about 30-45 minutes. The second round consisted of 3 back to back interviews with managers at their St. Louis Office. They paid for all the expenses of flying to and back from St. Louis. Each second round interview consisted of 4 behavioral questions and you had to have different stories for each interview. So in total you needed 12 different stories/ examples. All of the interviews were behavioral. There weren't any technical questions.
