I used myStaffingpro at my previous company as our ATS. It was our main tool for posting, collecting, and sorting through applications. All HR departments used the tool for their recruiting needs, it was a great way to stay organized, post openings, and proceed to the hiring process with candidates that had applied.
Taleo compared to myStaffingpro definately fits better for high volume recruiting and user use. It has a cleaner look, but all in all does the same function as myStaffingPro when you are able to have all modules from posting, to hiring, to onboarding.
When I used myStaffingPro at my previous position I was very happy with the program, it gave me exactly what I needed, was reliable, and made hiring candidates a breeze. It was a great tool for my position.
myStaffingPro is great for companies that are just starting out and looking for an ATS to implement. Being a small company their one-on-one attention is great and they make you feel very comfortable with using the tool. They also go above and beyond to be supportive and continue to come up with new solutions for your business needs.
