"If someone doesn't send a thankyou email, don't hire them."
This is the one rule Insider Inc's executive managing editor Jessica Liebman swears by when it comes to hiring potential employees — but it's sparked a storm of controversy.
Having interviewed hundreds of prospective workers, she penned an article arguing not sending a follow-up email is the "number one mistake" an interviewee can make.
"The truth is, the hiring process can uncover only so much," she wrote in Business Insider. "You're often basing your decision on a small sample of data that you collected during a few hours of speaking with them, sometimes not even in person."
She says hiring managers should always "expect a thankyou email", adding "you should never make an offer to someone who neglected to send one".
