regarding 压力,
all jobs have pressure, for new sales person, guess
this EXe title is not good enought for a sales personso so when you presnet ur name cards to clients, some clients may not seem willing to talk to you.
but a good sales person can always find a way out.
usually, for new staff, sales exe also need to do some paper work in the office, and there will be a manager to guide you, so the starting will be step by step, not as difficult as what people image. And then as a sales person, most likely u have ur own target to hit, if you can hit, of course no problem, if you can not, there might a bit pressure...
many companies like to employe new graduates as sales, so if your company employe you as sales, that means, you have some special highlights, dun worry too much, just try your best,
some of my sales friends are also 在新加坡做sales的外国人，they are selling different things here. according to my observation, they have something in common - work hard, 态度诚恳。
no matter what, good luck!
