I know of a story where someone shaved for a job interview at a non-Jewish company and didn't get the job when the interviewer told him how all the Jews in the office don't shave and you do.
My father loves saying this one over:
He was hired at Atlantic Records and he asked his Rebbe, Rav Shimon Shusholts zatzal, if he should get rid of his beard, tuck in tzitis, etc. The Rav leaned back in his chair and requested, "Describe your co-workers..." When my father was done listing dyed hair color and half-shaved heads and rings in scary places, the Rav smiled and said, "Keep your beard."
