I received a very good job offer Last Wednesday after conducting 3 interviews with HR, the Delivery Manager and the Program Manager. They were really nice and gave me extremely positive feedback, and even said they can't wait for me to join the team.
HR called me before sending the offer and said that she wants me to reply on the same day. The start date was set to be October 1st, as we agreed.
I replied to her email, accepted the offer but I did not sign it as both my first and last name were written incorrectly. I accepted within the body of my email and asked them to correct the spelling of my names, so I can sign it. A day after I resigned and agreed with my boss that my last day will be August 31, so again I emailed HR and informed them with my updated availability date.
It's now been 5-6 days now and I have not got any reply, when should I start to worry and how often should I be contacting them? I don't wanna seem impatient or show that I want the job too much but I already resigned so there is no going back.
