Minpunten
Lure people with promises of hiring permanently just to resolve technical issues at clients. I was at the end of a 6 months contract for a very large Montreal based company. I applied for the job on a job board on the internet and after 5 days I was hired. They told me they were looking to fill a full time permanent position that was vacant because the former employee left the company. During the contract I did my job very well hoping I was going to be considered for this permanent position. But that never happened because after I resolved many problems with the leftovers from the previous employee and everything was OK, they sent me a message by e-mail that they will not hire anyone for the position at this time. No reasons given. They didn't even have the guts to say it to my face even though I had many discussions with my superior about the hiring proceedings. Further more, after this message was received on the company's e-mail address, they cut all my access to the VPN network and mail account giving me a lame excuse that "it's procedure"...
...and I never heard from them again to the day...
Very UN-professional!
