One of the most important phases of working a job fair is the follow-up. It is crucial that you take this step seriously because like the first impression you made to the recruiter, this is what they will remember you by.
Another great point is that most students are horrible at the follow-up, so by doing so in a professional manner you will move up the ladder of consideration.
One critical mistake students make is not following-up with the recruiter after the job fair. This is a big mistake in personal networking.
You want to tie-down with context via email within 12 hours of meeting them. With context? Yes, you tell them it was great meeting them but you go further and re-state some items they said. Let them know that their insight made their company even more exciting in your eyes if that’s the case (they will love it.)
