Few weeks back, I had an interview with a company. They called me again for the second round interview and I think the result is positive. HR was also saying that they will mail me the confirmation letter very soon. I am 99% sure that I am selected. Salary has also been discussed. Here in my current company, I was planning that I will mail my resignation letter when I receive the confirmation mail from HR.
But today in the meeting my manager was discussing about a new project which they will assign me. But as I am planning to leave the company so definitely I will not accept the project but because I have not received the confirmation from HR, so I am confused. Should I tell my manager about my resignation before accepting the project or should I wait for their confirmation and add delay for the new project in my current company. If I tell my manager about my resignation and due to any reasons HR didn't send me the confirmation, then I guess it'll be a problem. How to handle this situation
