An interviewing technique to screen female candidates. The applicant interlaces fingers behind her neck and walks toward the wall. Should her elbows be the first appendages to touch the wall, the applicant is no longer considered for employment.
"Let's to the elbow test. First, lock your fingers behind your neck. Now point your elbows forward and walk toward that wall."
(elbows touch wall before breasts)
