回複：It is good news. Just go ahead, they are going to hire you

I only provided my coworker and previous coworker as my references, but I am not sure if it is strong enough.
I have sent an email to my previous director (who is the community chair in the area I am applying for) as my additional reference. Also do I need to mention my advisors name in school, who is a well-known professor in the major this hiring company is working on (The position I am applying for is a new direction in this hiring company)? Thanks
