QA Mentor Reviews & Testimonials
Software Testing Review from Lindsey Allard
They move really quickly which is huge for us as a startup. They are also very flexible. We added their team to our slack channel so now it’s so quick to ask them to test certain thing and they meshed with our dev team seamless.
Software Testing Review from Maria Musillo
Ongoing web application quality assurance testing including new features and regression testing. Additional penetration testing and site scanning. Ability to quickly assign a resource to a new project, little lead time needed. If a resource gets reassigned they do the handover on their end without being dependent on customer.
Software Testing Review from Domoniq Doby
QA Mentor has been an excellent on demand source for our immediate QA needs. Not only are they prompt and great at executing directions, they exceed expectations. They also have great integrity and are always responsive when needed, and not needed. I will continue to use them for my on demand QA services.
