In 2012 I worked for company A. I worked with A for tenure of 6 months. Then later I worked for companies B and C. Company D is my current company. In all I have 6 years of experience.
Both C and D are MNCs. I came to know that first company A is closed.
Now I have a offer from TCS. I have Appointment letter, Relieving letter, experience letter and salary certificate from company A.
The salary was paid in cash and there were no Salary slips or form16.
Also I have asked my senior (My lead not the owner) in the company A to provide the feedback of the mine if required.
Would this all be okay?
