I dont know whos employed some of the staff member but this particular recruiter SHES rude and thinks she owns the company or something. She NEEDS TO LEARN SOME TELEPHONE MANNERS BECAUSE SHE IS SOOOO RUDE AND NO OFFENCE BUT SHE SOUNDS VERY PATHETIC. Learn to have respect towards others, other wise leave and stay at home.

They dont pay their interpreters travel time, mileage or even parking costs. The worst company I have worked for in my ten years as an interpreter.

Low rates of pay for interpreters. No mileage, travel or parking paid. I did a job today. After using 5 for diesel to get to the job then paying 6 for parking. I basically made 4.

Not a great company to work for. Rule changes affecting interpreters are not explained sufficiently. Low rates of pay for qualified interpreters and no travel expenses. At least the payments are made on time.

As a freelance interpreter I must say it's one of the best companies I've worked for! They are really professional and I highly recommend their services.
