Did you apply for a job? I got an e-mail with this number but I think it might be a scam.

100% of all job offers by email, fax, phone, & text are fake. Everyone of them. Is it a scam? (You bet your asteroid kid)
(1) The salary & benefits are too high for the job.
(2) I am not qualified for the job, but they are offering it to me.
(3) The job is in Canada/USA, but I'm in another country.
(4) They are asking for money up front for (training/material/visa/etc.)
(5) They want my banking, and personal information
(6) I'm being asked to send money by a wire transfer (Western Union, MoneyGram, etc.)
(7) They use free web based email address' (gmail, yahoo, accountant, etc.)
(8) The company is real, but there is no person there by the name given to me.
(9) They want me to do a job interview by web chat.

I received an "unbelievable" job offer with the same contact number.  Said he was with an IT consulting firm in Canada.  Said his name was David Colby.  Website looked legit but 24 hrs later it was down. Hmmmm.  Apparently been using this same scam for 2 yrs.  Gets your info from Career Builder.

So they send me and e-mail talking about they would want me to send them my phone number which is clearly in my resume, then they had this lady call me for a phone interview with screaming kids in the background, she says if I get selected I would be given a call. I never received a call all the communication has been trough e-mail and text, then he finally calls me telling me his name is David Colby and that he is sending me a check so that I can get all the items I need to open his office. Then tells me I will be given the keys to the office which if u never met someone why would you trust them with so much responsibility. They honestly take great advantage of peoples need to get a higher paying job. :-(

Everything you mention I have also received from David Colby. How did you determine it was a scam?
