Foreign trade salesmen can't judge the quality of their business skills through one or two interviews. Recruitment interview can only examine their English communication ability, but also their English writing ability and familiarity with foreign trade English through English correspondence papers. I'm afraid other abilities can't be examined clearly in a short time. So you can only hire first, then try it for a period of time, and then decide whether to continue to hire.

If you are an export salesman, your ability to communicate with the outside world is the best. As long as you have a strong ability to communicate with the outside world, other abilities can be gradually cultivated in your work.

Of course, the best experienced export salesman is someone who has worked as a customs broker, inspector and witness and knows the performance, technical specifications and uses of the products he deals in, but I'm afraid such a person is hard to find.
