No. Mostly you run around collect business cards and then go online to apply for the jobs… that you could have done without going to the job fair in the first place.

TBH It’s a huge red flag if a recruiter wants upfront payment with no guarantee at the end of it (or even if they ‘guarantee’ one). If the recruiters are so desperate for someone they want to organise a job fair, they can bloody well pay for it themselves.
