TC7 has it right. All companies, big and small, have issues. The local Otis branch and how it is run will influence how you are treated the most. You have competed against them, so you have a unique perspective on this. How have customers you have nicked from Otis said they were? How have employees who have come from Otis, or guys you have lost to the green machine, said it was? Any of your infrastructure staying or is your whole team merging with local Otis office? What position are they claiming to keep you employed in for 10 years? Will the employment be guaranteed at that location?

These are the sorts of questions you want answered before you can even consider a response.
