"Acknowledgement"

If you insist on getting an answer regarding a job post (requested 3 times), you should "at least" reply back saying "Well received" or "We will have your resume in mind" or "We are looking for another kind of experience", etc.
I spent my time answering a long set of questions/requirements (as well as many other professionals, I guess) so the polite thing to do is send an acknowledgement, in my humble opinion.

"Rad Hires is amazing!"

Rad Hires has been an amazing nearshoring company to work with. Highly recommend them!

They have been great in finding talented developers at reasonable prices for my Shopify Agency.

"Trust"

Whenever I need Software Engineers, Rad Hires is my go-to recruiting company. They are incredibly easy to work with, very reliable, and they provide clear communication and expectations throughout the entire process. If you are looking for onshore or nearshore software developers I highly recommend them!
