Job offer came in! after 18 years as an accounts payable clerk

They called on Thursday with an offer and I said yes right away. I have read a lot of threads here and could not find my exact situation. I am relieved and a bit nervous. Any advice for starting over?

Congratulations! Take notes on names and processes in your first week. It helped me settle in.

That is wonderful news. Keep applying for a little while if you have not signed, it is a good habit.
