Thank-you notes are a nice gesture, and I would always encourage candidates to follow up with one after an interview. However, as far as influencing a hiring decision, I have yet to see someone being extended an offer because of it. The strongest candidate will get the offer. Every little bit helps in marketing yourself as the best and most enthusiastic person for the role. If you do send a thank-you note, always check for spelling and grammar!

写感谢信是很不错的选择，我经常鼓励候选人在面试之后写一封感谢信。然而，说到感谢信对雇佣与否的影响，我还没看到有人因为这个而被给予一份工作的。最优秀的候选人会得到这份工作。每一件小事情都能够帮助你包装为适合这个职位的最完美最热情的候选人。如果你发送了一封感谢信，要记得检查拼写和语法。

Sending a thank-you note is a must. When a job candidatesends me a thank-you note, it shows me the person is truly interested in the opportunity. This simple gesture can distinguishone applicant over another. In fact, when considering multiple people for an open position, I typically recall who has and hasn't sent a thank-you note.

发一封感谢信是必须的。当一位工作候选人给我发送感谢信的时候，我会认为他真的对该职位非常有兴趣。这么简单的一个动作就可以看出一个人的区别。实际上，在考虑同一个工作职位的众多求职者的时候，我通常都会记得有哪些人发送了感谢信，哪些人没。
