Can I see the current employer's experience letter?

In this question the Visa Officer is asking about company or firm that you are working currently.

Don’t panic with this as you won’t have your current employer experience letter as you are currently working with you’re them.

Answer:
I am currently working with them so I don’t have the experience letter, but I have the offer letter from them.

Then give the offer letter to the Visa Officer. If you got promoted after you join their company it is good to show the promotion letter also along with the offer letter.
