Move Quickly

"Once you find a candidate who can meet your needs, you should be ready to extend an offer pretty quickly," says Clem, who advises businesses to have a planned timeline to get someone on board.

After all, you don't to let someone who is a good fit slip away or lose interest – and many apparently do.

Fifty-seven percent of job seekers say the time they wait after an interview to hear back from an employer is "long," Clem says, citing Robert Half data.

How long is long? Thirty-nine percent of candidates say a week to two weeks, while 23 percent say just one week.
