Toxic leadership with no diversity. It's a good ole boys club from flyover states that run the place like a high school cafeteria. Beware of the microsoft unit, as they will require you to sign an Non-compete at time of hire which prevents you from working at any of the other hundred Microsoft partners in the future.
Core is a chop shop of acquisitions owned by Tailwind Capital (check out their reviews) with 3 acquisitions already in 2021. The plan is to keep buying companies and then sell it all. A nightmare for engineers, sales and operations. The smart ones have figured it out and left (10+ billable resignations in the last month,) others are stuck because of the Non-compete or commission schedules. Core does not finish their customer projects and will bill you all the way to the bank.
The short ambiguous reviews here are a clear attempt by HR to portray it as something better than it is.
