As someone who had a chem degree AND worked in pharma sales I can tell you that A) undergrad chem degrees don't get paid shit in any lab anywhere, and B) pharma sales makes OK money but nothing mind blowing, provided you can even get a position anywhere in the first place. Pharma sales industry has been shrinking for a long time, and unless you know the actual team manager knowing someone who is a pharma sales person won't do you any good because they don't get to decide who to hire. Also the whole "it's a big ol boys club" is completely false, the teams I worked on actually had more women than men, and large pharma companies like any other major corp nowadays tries to avoid sexism and the like as much as possible since they're so heavily scrutinized.
