I will begin McK's background check in the next 1-2 days as I've just accepted the offer. However, I have a competing offer and don't want to turn it down until my background check with McKinsey clears and I'm all set there.
How long does this process usually take? And does McKinsey do reference calls in top of employment verification? Wondering if I should reach out to previous managers/colleagues to give them a heads up if I end up listing them.
