Quote from dandxg:
You have to be careful about what you say to them. They could be working you for leads. Oh and where are you interview, their next call. I worked in the industry for about a year as my first sales job.
One time I heard our recruiter do just hat. Found out where prospect was interviewed and cold called those businesses with our signed up prospects.
In an nutshell, like brokers they can be very sleazy.
The moral of the story is if you do speak with or meet with a staffing firm, don't tell them the companies that you interviewed at, otherwise, they can then contact those companies, try to obtain a recruitment agreement with them, and then send their candidates to that company. If you are still being considered for employment with that company, now you will have more competition to deal with as the staffing firm starts sending them more candidates.
