ES actually has really good products, and their reps used to make more money than any other division; futhermore they are the only ConMed division that doesn't sell off of price. The problem is the management. They do many different things that cut off their nose to spite their face. Believe me if you go to ConMed ES you will regret it, the last thing you need is someone forcing you to be a one legged man in an ass kicking contest.
I like what the previous poster said about emailing people from linked in, and can only think of one thing to improve on that, which is if you want to get a fair reply, email someone who has left ConMed ES. Typically, reps will speak highly about old jobs if the company was fair, and if the company sucked, they will be positive but non-specific because they feel bad about steering you away.
If you join ConMed ES, in the end what will happen is you will not be able to compete with the big players, then when you try and leave you will have to explain why you were under quota all your years at ConMed to the managers you are interviewing with. Statistically, very few reps make quota. You want to go to a company that is managed well enough so that 60%+ of reps hit quota. I say you interview, and if you are offered the job turn it down, and use it as an example for other interviews. This will give you an infectious confidence that other employers will gravitate to, and show others that you are of high quality because you are not willing to take just any med device job.
