Main problem about those job fairs and mandatory offers was that it never resulted in actual employment. Those "fairs" had 20 job posts ranging from Amazon work camp through shady mining job in some forsaken hole up to wiping asses of old fash in Germany, and those mandatory offers were also either scam jobs or telemarketing and the real purpose of it was to make you lose time and money and make you pissed off so you write off yourself from the office list so they can report lowering unemployment.
