Companies play all kind of games.
Friend of mine took a job offer, quit his job and showed up at his new employer. They told him he was in competition with 2 other new hires, all for one position. The other two guys had also quit their jobs also.
It was for a training position and the three of them had to do a presentation showing what their skills were. My friend gave the best presentation and was hired, the other two guys were out of luck. They were paid for a couple of days, so legally they had been hired and fired, but in reality they never actually had a job.
Sounded like lawsuit time to me, but who knows if an attorney would even take the case. All the employer had to say is that the guys didn’t have the skills, etc.
Sometimes they put job openings up there to try to pull out info out of applicants, because they are having problems.
They do not want to hire anybody, but under the job interview process, they try to get the info from the applicants!
