I applied through university. I interviewed at USAA
Interview
The first interview was an on-campus (College) interview. This consisted of simple behavioral questions, and some innovation questions (E.G. Describe how you would make a system for <business case>). There was a math question as well, but it's not difficult, nor is it necessarily important to solve it correctly.
The second interview was an on-site interview in San Antonio. They gave a panel interview and asked very similar questions to the first one. They tend to focus more on how well you have worked in a group in the past.
