Alternate documents for Employee verification?
My new employer asked for my previous offer letters and salary slips. When I inquired, they said it was for background verification.
However, I feel that providing these documents might affect salary negotiations, and it feels a bit unethical too.
What alternative documents can I provide for employment verification?

Interview Preparation Tips
Interview preparation tips for other job seekers - Never believe Deloitte Company. HR would give promises after finishing the HR round which is the last round in most of the companies. Later, they scheduled another round immediately without informing prior and informed that you got rejected after that round.
The candidate gave a counteroffer letter to HR and HR was fully aware of the joining date in that company. But still, HR made a promise on the phone she would give the offer letter a day or two days after the final round ie, HR. The next day HR called me to go through another round with the director and later said you got rejected. The candidate rejected the counteroffer letter and listened to the words of Deloitte HR's promise. So never believe these HR representatives of Deloitte, they will make you go jobless. Very PATHETIC experience. BEWARE OF SUCH FRAUDSTERS.
