I start a new job on Monday - 18 weeks in

They called on Wednesday with an offer and I said yes right away. This is my first time dealing with any of this. 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.
