I applied online. I interviewed at USAA (Telephone, TX) in Jul 2017
Interview
Professional but not rigid, relaxed and business friendly, about twenty minutes long. That was initial interview, second one today. Many generalized questions, such as give an example of when you went above and beyond for your employer.
Easy and super fast, it took me 2 weeks total from applying until getting an offer. Phone screen interview, and then in person with hiring manager. In person took about 30 minutes
After filling out the initial application I was invited to take an online skills assessment which included timed portions and was fairly lengthy. There was also a brief phone screening, and then an in person interview with the manager.
Very specific questions. Be really prepared to come up with a story on the spot. Nothing to do with the job description. They want you to sound like a robot.
