[originaltext] Every candidate knows the significance of the interview, but

Every candidate knows the significance of the interview, but may ignore the post-interview period. When you walk into an interview, there’s a good chance this hiring manager doesn’t know if you’re the right person for the job yet, and when you walk out of the interview, he or she may still be unsure. That means, your follow-up communication can make a difference. For example, (29)sending a thank-you note after the interview is a good way to ensure your success. When you write a thank-you note, there are three points you should remember. Firstly, an e-mail of thank-you note is better than nothing, (30)but a handwritten note can set you apart from other candidates. Nowadays, handwriting letters are powerful because no one sends them any more. Secondly, the thank-you note should be brief. A rambling note wastes the hiring manager’s time, and it can suggest that you lack the confidence of consciousness. (31)So the manager must like to read a brief note. Besides, (30)the thank-you note should be specific. Your note shouldn’t read as though they could be reproduced for every interview. If you put things in the note that connect the interview with something you talked with the manager about, it shows you are paying attention to the interview. All in all, a good thank-you note can help you succeed after an interview.
