Same thing with me in oilfield. Apparently they don't like heights and -30 degree weather with extremely long hours.  Had 1 or 2 inquiries due to a bad job description in my post but it never made it past my answer to the job description question. It was aghhh thanks. Pays extremely well and entry level pays the same regardless of gender. I'd even be willing to take the chance on a female working out. Just never happens.
