# The hidden costs of engineering time in technical interviewing

As such, in this post, I’ll throw out two ways that we can make the cost per hire calculation more useful — by including eng time and by breaking it out by candidate source — and try to quantify exactly why these improvements are impactful… while building better rapport between recruiting and eng (where, real talk, relationships can be somewhat strained). Therefore, with ramp-up and ramp-down time in mind, it’s more like $9,000 in eng hours.3

Ultimately, for one hire, we’re paying a total of $10,500, but eng incurs 6X the cost that recruiting does during the hiring process. It turns out that eng time spent IS a lever you can pull, and its impact becomes clear when you think about cost per hire by candidate source.
