It's not a hard and fast rule. But usually, USUALLY unless someone was a supercalifragilistic candidate that stood out MORE than the others, the calls don't usually, USUALLY go out that fast.

Often times, they're STILL sorting/sifting apps from the LAST fair or whatever for months after the event. NEVER MIND all the other application silos and stacks they're culling from.

Not long ago, it seemed like some of the OBAP/WAI and normal job fair attendees had a coincidental 3-4 month period from last recruiter face time to interview invite.

I say AGAIN, USUALLY. I know, I know, some holder of massengil product is going to say "well I (or someone I KNOW) went to (insert event here) and got a call the very next week!!!!!"

Well, good for that person. But read the FIRST part. Usually, USUALLY takes them a while to sift/sort compare rank rack and stack.
