Quoting Redneck mamma:" I wonder if children whos parents misspelled names are at a disadvantage when they get older because ... [snip!] ... come from a dumb family? I know they typically through out names that are horibbly misspelled when looking at job applications."
I majored in HR and honestly? HR people DO tend to avoid calling people back whose names look over the top ridiculous to try to spell or pronounce. It's not even their idea, sometimes - there are people who I have talked to who were INSTRUCTED to not both with people whose names are difficult.
This is especially true if they are hiring for a position that deals directly with the public. Yeah, it's not fair - but when it comes down to it, people are more likely to approach you if they can pronounce and understand what your name is.
