It has happened to me before to take a job and then find it was completely different deal from what I expected. I really don't want something like that to happen to me again.
Any ideas on how to get a sense of work environment at a new place of work before leaving your old job? (Yes, I'm scared I'll regret leaving Avaya.)
No, I mister Avaya.
Do you miss Avaya?

Have to do what's best for you but realize that "change is constant".

Read a book called "Die Broke". Seriously, not kidding, it will open your eyes and change your life.
