Depends on the interview, they won't just give you one. If they decide to keep you, they will interview you and keep those that perform well. You can be a manager, if they are going to build out the software, you can be a VP for that product if you demonstrate competency. Best of luck.
Thanks. They specifically want to keep us to integrate our tech - but with huge modifications - almost like building from scratch. The deal is more of acqu-hire than acquire the product & users.
