If you have all qualifications, 43 shouldn't be a problem. B.A./B.S. degree, proven track record in sales, good GPA and interviewing skills. The bigger question to ask is "is this really what I want"? What do you do now???
No, if you don't mind being unemployed at 44. Seriously, if you're looking for a long term career look elsewhere out of pharma
Unless you have prior experience in pharma it is almost impossible. There are so many displaced/laid off people ahead of you that you never get a real look. If they have a quota for a number of interviews they have to do, you might be called but never advanced. Look elsewhere because even if you get in, as others have said, you do not have a safe career path.
43 yrs old, have a resume with 20 plus yrs experience...(hopefully positive) and somebody in pharma brings up your grade pt average?? Great question for recent college grad. but really who give a flying f ??? is the toss up decision going to be the gal with a 3.0 (but with lots of science for a BA degree) or the guy with a 3.7 BA Communications??? Really if you're asked that, that alone answers alot of questions about pharma.
