What is the process for a recent college grad to join the Army as an officer?

For a recent college graduate, ROTC is still an option if the candidate wants to pursue a Master's degree. The candidate would then go for another two years of school and enroll in the advanced leadership half of ROTC (MSIII/MSIV).

See a recruiter. Take the asvab. Don't let them talk you out of it and enlist instead. Put together a packet through the recruiter. Go to basic. Go to OCS. Choose a branch based on your performance at OCS. Go to that branch's Basic Officer Leader Course. Go to your unit.

The most difficult part would be the letters of recommendation and the board to get selected. If she wants to be an officer don't let the recruiters talk her out of it in order to enlist. It's less work for them to enlist people. They will push for it.

Correct, she would enter in as a 09S (Officer Candidate), E-4 and once she completes Basic, she will attend OCS. I had 1 09S change his mind mid-way through basic and continued as a 25 series.
