I had the first interview over the phone with an internal recruiter who reached out to me about the role. The recruiter asked a question about my background and while I was answering I got interrupted with: "Oh, I need to ask, are you legally authorized to work in the US?" I have an accent, but I am a US Citizen and she obviously noticed the accent and had to make sure right away! We moved on and continued with the interview, however I got the impression this recruiter felt annoyed or impatient by my accent while I was answering her questions which was uncomfortable.
