Pros
Absolutely nothing. Just a bunch of Indian crooks taking advantage of U.S. cash
Cons
They publish and spams unrealistic jobs by the hundreds. "Remote, $300k, $100k signing bonus, 8 weeks vacation, no background check, etc etc". They are simply collecting names. If you reply in any way, they've got you. Now they've confirmed you exist, and your resume is real, and a line of communication has been established. And they'll use it to brag to some poor folks looking for a resource staging "we have thousands of active U.S. resumes on file". USTech and a handful of other small U.S. footprint companies are in this game to dilute their Indian, Pakistani, Chinese, South American staffers with as many U.S. resources as they can. STAY AWAY FROM THESE CLOWNS
