I didn't notice that your designation at the time of joining the current establishment was Senior Engineer. As advised by Lakshmi Narayan, you cannot join as a Senior Engineer without having experience in hand. Now my question is, whether the company where you have worked for 2.10 years really exists? Is it a fake organisation? Or how did you manage the background verification then? It may happen that by luck, the employer should not have sent it for verification. Or did you have any strong hold in that fake certificate company to give a good endorsement for you? If yes, continue that. We should not encourage fake certificates and in order to cover up a wrong thing we are again and again doing wrong thing and it is endless. But at a certain point, the background verification beyond a certain period will become impractical. Normally, background verification may be taken from three employers and not more than that.
It is upto you to decide and take a call.
