ASVAB, you start as a Seaman Recruit, then move towards your promotion. The promotions usually happen in time. Then once you reach E3 or Seaman, wait 6 months to take the 3rd Class exam. You usually take exams 2x a year. Studying is required and there is a minimum percentile required to pass. The quotas change every exam date.
There was no interview process. You, however, must meet age requirements and fitness standards. You must also pass the entrance exam, known as the ASVAB to determine which roles you qualify for.
There was no technical interview process. The recruiter did ask questions. Essentially all I had to do was talk to a recruiter, take the ASVAB, go through a physical exam, and sign a contract.
