They contact you online through Facebook or etc
Then maintain communication through WhatsApp.
They confirmed project immediately (only to inform me I wasn't going to be on it two days prior to start).
Just be wary , I dealt with this in Switzerland
Cons
Be careful they don't care about you , only the profit they make. often they guarantee you a job and cancel or completely alter the time to suit them and their 'client' requirement. This mean that you may free yourself or turn down other job opportunity only for them to cancel on you last minute
