Should I write a thank-you letter after an interview?

Writing a thank-you letter after an construction interview doesn't just showcase a construction executive's manners - it can also make or break their chances of landing a job. Nearly 15 percent of hiring construction managers say they would not hire someone who failed to send a thank-you letter after the construction interview. Thirty-two percent say they would still consider the construction executive, but would think less of him or her.
