I believe I have read a study (can't dig it up) where a simple switch to a female name in the context of a technical job made the response rate drop.
I graduated with a BSME from Nebraska, and my first name is Earle. I went for ~3 months without any responses to resumes or applications, until I added my middle name. I started working a new job within two weeks, and now have to go by my middle name at work. All because "Earle from Nebraska" must be a redneck hick.
My case is almost certainly not racially motivated, but literally the only change I made was my name.
i'm an asian guy with an ultra generic anglo first and last name and i've never really had any trouble getting interviews. in fact when i show up and i'm asian they usually have a nice little chuckle and are pleasantly surprised. generally asians in technology at the worker-level don't get discriminated against unless they have thick accents (which i don't).
i've seen resumes with asian first/last names that have a note under the name that says "natural born US citizen, authorized to work anywhere in the US and territories" or something to that effect. it's a good thing, in my opinion. it signals multiple things in one neat little sentence.
