Ugh. Also Latino (and California!) and I was looking for native Spanish speaking supervisors during internship. I asked every site whether they could offer supervision in Spanish...and got a few cringe-worthy answers.
At one site the TD replied something like, "I only know the most important Spanish phrases -- how to order another beer and how to ask where the bathroom is." The other interviewers laughed and I was speechless. Another site, again the TD I think, replied something like, "I speak enough Spanish so that I could tell a 2-year old to sit down and be quiet." Again, laughter from the other interviewers and crickets from me. I'm not even sure what they meant by that comment.
IIRC, the after-match survey explicitly asks about inappropriate questions/interactions during interviews -- I hope you'll share your experience there too.
