So how has tie guy worked out? Did he make a good hand? If not, I guess it was probably cause of the tie.
I've seen enough of your posts know what you do, and which company you work for, so I do respect your opinion. Fact is I agree with you to some degree. But it's not like the OP is planning on waltzing in wearing an Armani suit. His description (boots, khakis, button up, sport coat, no tie) sounds like something a team roper from Marfa might wear to Church on Sunday. This appearance (respectful & yet still blue collar) is pretty dang appropriate for a MWD interview.
While I've never had a job that involved much hiring or recruiting, but I've worked in O&G long enough to know what to wear to an interview. And I'm plenty familiar with the job and your employer, probably more so than you are. I've never heard of managers rejecting people because they wore a tie. Sounds pretty ridiculous to me.
OP, you've got a couple of different opinions here, so just do what you think is best. In the end I don't think your choice of jacket type will make huge difference either way. That being said, if you and KT Ag08 have some kind relationship outside this forum and he personally knows the guy who will be interviewing you, follow his advice.
