A few tips for the end of the interview…
It’s okay to ask when they expect to make a decision.
Thank the interviewer(s) and express your passion for their business.
Write down everyone’s name and title with whom you interviewed.
Write each of the interviewers a thank you note using blank thank you cards from a stationary/office supply store. (NO “humorous” or “cute” cards).
Write the thank you on the day of the interview and mail it immediately.
Be sincere, not obsequious.
