My wife is  preparing for a junior-level pharmaceutical sales job interview
at the local job fair event in North Jersey. She is planning to target
Wyeth, Merck, Johnson & Johnson and TAP Pharmaceuticals.

I would value your thoughts on their value proposition, market
position, and main drugs from potential Sales rep's perspective. 
Maybe you know of some competitive alternatives that each of these
company's sales executives worry about?

My wife has 3 years of Sales experience with Glaxo Smithkline from
foreign country. But currently not working in Sales (last 3-4 years
working as Pharmacy Intern in Pharmacy-chain) but wants to go back to
Pharmaceutical sales career.

For this sales job she is planning to work in & around North NJ. So
she is targeting all of North Jersey (Morris, Bergen, Passaic & Essex
counties).
Just high level ? no need to dig too deep.

I appriciate if you send the info ASAP as there isn't much time
between now & interview.
