I am in my job changing period, currently serving my notice period. 2 weeks back, I have given an interview, the interview went pretty well that they wanted me to sign the contract immediately. I have asked them for some time to think it over and decide. They gave me the sample contract, so I can read and go through it! They informed me that once I talk to my boss and clear things up, I can sign the contract at their place.
It is a very good opportunity for me. So, I have decided to take it. I have talked to my current employer, he accepted my resignation without causing any trouble. Now, since last week my new employer (HR guy) is acting a bit weird. He hardly replies to my emails, never takes any calls. This might sound like, I am annoying them but I have asked them to clarify my salary package and raised a couple of concerns regarding what they have proposed. [so 2 emails, 4-5 phone call attempts over 3 days span]. I have finally settled with them this issue. He told me that he will prepare my contract and invite me for signing exactly 7 days back. It has been 10 days already that I have resigned and still I am waiting for the contract to sign! Here in Germany, we had a long weekend last week but HR clearly told me that it will be done by 02.05.2018. Yesterday, I wrote him an email and today I tried to call him and there is no response yet!
So, was it a mistake from me to resign the current job before signing the new contract? This is my first job change, so I am a bit worried if I have messed it up! Should I wait for their contract? or resume my job search again?
