I'm old enough that we didn't really have those technical things when I would have been enlisting (early 90s). But even then I remember our guidance counselor telling us, "You'll get 5 calls. One from each branch, all asking you to enlist. You can just say no."

We all took the ASVAB, as I recall - it replaced a class period. For some reason, I remember the room I took it in, so I'm pretty certain it replaced a language class (German, in my case - it was a small, windowless room, though I did have a study hall in the same room one year). When I met one on one with the guidance counselor, he looked at the ASVAB and said, "Well, you're qualified for every job in the military, but you're probably not interested." Then we talked about other careers and college.

Now that I think about it, that dude did me a world of good on several occasions. I wish I could find him and thank him.
