Using a company iPad privately
The iPad will allow you to run any app installed on it, no matter what Apple ID it is associated with. You will need to switch to your account when you first download the app, and then switch back. The app will continue to run normally, and if there are any updates you can download them without switching accounts (the App Store will ask for your account's password). I am not sure which account will be used if you try to make an in-app purchase, though, so be careful.
