If these details are true,why do you have to worry??
As long as you have given correct details of experience there should be no problem.
Thanks for your replies,
I have offer letter, experience and relieving letter of that company with me and I'm still in contact with my old owner. He will verify my employment in his company.
What I fear is,
They might ask for form 16 (or) email communication with employer (or) salary deposit report from bank, I don't have any of these things with me since my salary is paid to me in cash and I didn't pay any tax during that employment.
Will this be problem for me, please guide me.
Note: I have all of the above mentioned documents (form 16, email comm. & salary deposit)with me for my current employer.
