I cannot speak to the organization as it exists today; it is my understanding there has been so much turnover since I left, I would have very little idea what the current makeup of the company looks like.
That said, when I left it is not somewhere I would ever consider returning. Much of the reason for this is due to the complete vacuum in terms of management support and innovation, the life's blood of any company like this.
On the positive side, people outside of management were friendly and did their best to be helpful. I would definitely consider hiring people from Molecular Devices, but I would never recommend working there to anyone.
