Honestly, take an objective look at this industry and try not to get disgusted. I did that years ago which is why I left.
I was at a trade show within the past few months and ALL of the sales reps. they had were women under 35 and easily 8s on a scale from 1-10. These were not booth babes you rent.
I went into device and am a very average looking man (hey I can admit it, who cares?). Most of the people on my team are average as well, and my competitors aren't particularly good looking either (men and women). I've come to the conclusion that in real transactional sales, they just care about being corporate and results. When I was in pharma, most of the women were good looking and even the average ones were ones that with a few beers in me i'd be happy to say I banged to my friends.
When your job is a walking commercial, of course you have to be good looking. Sex appeal sells.
