Hi, recently I have joined an MNC company after working in two different companies. I came to know that my first company closed 3-4 months ago, but they were still providing email and call support for background verification to previous employees. My doubt is, will that company be considered a fake company now that it's closed? I have all the necessary documents like offer/relieving/experience letters and payslips. What would be my situation if my current company finds out about this?
