Their wide reach and ability to dig in. They are strong globally and can go deep into the weeds to find exact fits instead of just scratching the surface. They almost always give optionality when it comes to picking the best fit while some other companies strongarm us into picking anyone that broadly fits our criteria.

project leads were thoughtful and seemed to know what they were doing they presented qualified and interested people for us to select easy decision for us since 4/5 of the people they presented were qualified

I liked how myself and three associates didn't have to do much. Our zintro project mnagers organized each participant list and showed participant qualifications for us to review. We picked the ones we liked and they took care of scheduling and paying them. All but 2 of the 150 participants were really good, and for the two that weren't, we cut the call off before 10 minutes and Zintro found us two replacements that day. Strong management and organization from their two PM's.
