Don't let a work gap cause you to miss a good candidate.
A couple of interesting studies examined the extent of discrimination against the unemployed. These studies are unusual in that they involved real efforts to find real jobs. One created 3,000 pretend candidates and sent their resumes to a random sample of job openings. They varied one item among otherwise identical applications: whether the individual was currently unemployed and, if so, how long they had been unemployed.
Only about 4.5% got callbacks, which suggests that the typical unemployed applicant has to apply to a little more than 20 jobs to just get a positive response from an employer indicating that they are still being considered for the job.
