Interview
The process to become an officer in the US Military is long and requires a lot of patience. There is an in person interview, background check, multiple IQ / Competency tests, there is also a personality test. If you are accepted you spend either 4 years in ROTC through college or 3 months in intense "Boot Camp" Style officer training school. It's not easy but it is definitely worth it.
