Towards the end of your interview you should have asked the key question about what happens next. Something like “How soon will you make a decision on whom you plan to hire?" This will have given you a time frame; you want to appear enthusiastic but not annoying. If they expect to make a decision within the next week, you need to follow up in a couple of days; for a longer time it is best to wait a week.

　　到面试结束的时候，你应该询问的一个重要问题是：接下来会怎么样？比如说，“你们决定录用一个人的时间要多长？”问这类问题可以给你自己一个时间范围，而且你体现了你的满腔热情，而不是满心焦急。如果面试公司会在下周内做决定，你需要在接下来两三天内保持跟进；如果面试公司需要更长时间，那你的跟进时间差不多在一个星期左右。

　　One thing you should do, immediately after the interview, is send a thank you email or letter. Send it the same day or, at the latest, on the following day to the person or persons who interviewed you; remember to ask for business cards before you leave the interview. It is a good idea to do this even if the job doesn’t really interest you. In it you should show your appreciation for the employers’ interest in you and stress your interest in them.

　　面试结束后，紧跟着你就需要做的一件事，就是发出感谢信，用邮件或信件方式都可以。在面试的同一天，最迟第二天，要寄到面试官手中；离开面试考场的时候，记得向面试官索要名片，以确保得到正确的邮箱地址。哪怕这份工作不是你最理想的，寄出感谢信也是不可缺少的一个环节。在信中，需要流露感激之情，原因是雇主对你感兴趣，同时也要强调，你对他们也很期待。
