After the Interview
After your interview, be sure to write a thank you note. Sending a thank-you note after an interview is a great way to make a positive impression and stand out.
First, it shows professionalism and courtesy. Taking the time to thank the interviewer for their time reflects well on you and demonstrates that you’re respectful. Plus, it gives you a chance to reinforce your interest in the position. It’s a subtle way to remind them that you’re excited about the opportunity and still very much interested in the role after learning more about it.
A thank-you note is also a great way to highlight key points from the interview. You can use it to briefly touch on things you discussed, especially where your skills and experience align with the job. It helps keep those points fresh in the interviewer’s mind.
