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.
Questioning the Existence of Previous Employment
Now my question is, does the company where you claimed to have worked for 2.10 years really exist? Is it a fake organization? Or how did you manage the background verification then? It may happen that, by luck, the employer did not send it for verification. Or did you have any stronghold in that fake certificate company to give a good endorsement for you? If yes, continue that.
The Problem with Fake Certificates
We should not encourage fake certificates, and in order to cover up a wrong thing, we are repeatedly doing the 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 up to you to decide and take a call.
