Checking Wikipedia, I see:>The term Hispanic (Spanish: hispano or hispánico) refers to persons, cultures, or countries originally related to Spain, the Spanish language and culture, or to Spanish America.
So, I would understand the term "Hispanic accent" to refer to an accent typical of someone whose native tongue is Spanish.>>7117>>7121
An accent that is difficult to understand will definitely be a problem. However, I don't think this is a problem for most native Spanish speakers (unlike native French speakers).
It is true that many Americans associate a Hispanic accent with lower-class jobs, especially for people with darker-colored skin, and this unfortunately might lead to subconscious prejudice. If you're applying for a STEM job, where qualifications can be evaluated fairly objectively, this would probably be less of an issue than for jobs where the evaluation process is more subjective.
