They keep calling us back
I’ve been working with the Partners at StellarMettle since 2016, and they have consistently outperformed other recruiting firms with the quality of candidates they’ve produced that also fit my workplace culture. I’ve worked with many staffing agencies in the past, and this is the only one I’ve used for exclusive placement of positions, that’s how confident I am in their ability to fulfill my staffing requirements.
We used StellarMettle to fill several “hard to fill” roles in my organization, including but not limited to: Data Engineering Manager, Senior Data Engineers, Cloud Architect, and DevOps Principals, as we built out our data lake, AI / ML Ops team. They were most professional and listened attentively to our needs, trying to get the requirements, job description and particular nuances for the roles right in the first few meetings. They literally did “shake the trees” and discovered true gems in a tough market like Atlanta, who proved to be great hires for us! They exceeded our expectations in their ability to find, screen, and prequalify the candidates, as shown by the quality of candidates presented. Their ability to respond to our feedback, and keep improving the funnel was outstanding, saving us tons of interview hours. They facilitated the entire process from interview, to offer acceptance, with a very impressive offer to hire ratio, better than any other sourcing company we have used in the past, or even used simultaneously for the same roles.
StellerMettle are experienced professionals that deliver with a high say-do ratio with the right candidates for the job. My managers have been consistently impressed with the caliber of the team’s candidates presented, as well as the professional methods they employ in our relationship.
StellarMettle has assisted with placing several members on our team. Every submission was tailored specifically for the role, they were vetted, and were extremely relevant to the position. I couldn’t be happier with the level of service and support I’ve received and would strongly recommend StellarMettle to anyone looking to fill a role.
I’ve been working with StellarMettle for many years now, over a decade. They have been able to recruit phenomenal talent, matching our high standards and sought-after skillsets. It’s been easy, efficient, and fun to work with their team. Highly recommended partner!
