Multiply that by the number of jobs someone typically applies for when they want to change role and you're likely contributing to someone not seeing their family or friends for almost a month. Also... Is that 2 days total dev time, or a deadline that's 2 days away? Someone with few responsibilities and a willingness to forego sleep is likely to put in far more time than someone with a family of the deadline is two days away.

It sounds like your interview process is designed to push away people with families and friends. Let me guess... Those great hires really put in the extra hours?
