After a lengthy process for a company that in theory cherishes diversity and inclusion, self-declares it works to empower local communities, and was founded by an immigrant - I was shocked to hear that my immigration status was the reason I did not receive a job offer.
I provided all my documentation in advance - which by itself falls under the discrimination law by USCIS ("A part of the Immigration and Nationality Act, found at 8 U.S.C. section 1324b, prohibits employers from discriminating against individuals based on their citizenship or immigration status, or their national origin, during the hiring, firing, recruiting, Form I-9, or E-Verify processes").
A company that does not reflect its values in its actions is doomed to fail.
Immigrants should be aware of that before investing their time at DoorDash.
