Do yourself a favor and avoid Publicis. I don't know your situation, but after being laid off from a "real" drug rep position elsewhere, I took a Publicis job because my severence package was close to running out, & we just had a kid.
I had no idea how much taking a contract position would set me back in the industry's eyes when it came to finding a new job. My manager was canned & he couldn't find a sales position even with a management title.
Now... With that being said... If you are under 30, are a very attractive woman, and the manager of the territory of the company you are contracted with is a man? Go for it. The odds of you being hired by the contractor are definitely in your favor. I know that sounds jaded, but it's true. But if you are a seasoned rep who needs the income, then my advise is to look elsewhere. Because a year or two will go by, and all you will have to show for it on your resume is a job that you will need to explain your way around in any interviews with legitimate employers.
I wish someone had said something like this on a post before I worked for that awful place. I don't even know why I came back to CP today to put this post on here. I guess I just don't want people to make the same mistake that I made. Publicis is a French Company with one thing in mind; fill a position for half the price. You will never be a priority to them. And who wants that out of life?
