Don’t know whether they still exist. But I worked at IDT, for 3,5 years. Started less than a month (seriously) after moving to E”Y and stayed there in 3 different projects for a total of 3,5 years. Without them I would never have made it.
(They had, back then, jobs in not just English but in several other European languages as well – basically, every possible European language. We even had Finnish-speakers!)
