They definitely do offer jobs after job fair, but you have to be a great fit. Remember, they interview about 6-7 people in one day for each position. Last year I had 7 interviews and got offers to most, but my SIL had a lot less experience than me and did not get any offers. She was still able to get a job' just after job fair. What is your experience for the position you interviewed for? Do you know the curriculum for that position?
