I have applied to a new job, and the process is going well.
I have asked for a salary of 100k, around 40% or 30k more than I earn today.
There is an upcoming interview with HR, and I was told my an ex employee that they usually ask about current salary.
I simply do not want to disclose my current salary, I am afraid that can influence their offer. I also feel this is personal, and not related to the negotiation.
Is it possible, somehow or after the offer - In Germany - That an Employer discovers or checks my current/previous salary?
If they push me to share, what should I say?
Can I keep my working contract just to me and my employer, or I need to share those things with future employers?
Please note my question is directed to Germany's working culture, laws, etc.
