Regarding initial non-disclosure of facts during interview

3 years ago

I have joined a prestigious central govt. organisation X as a group A gazetted officer recently two months before. Previously I had worked for hardly a month in a PSU Y as an assistant Engineer. During the interview in the Central govt organisation X, I was employed in Y (but it had been only 10 days). My Mistake: I did not disclose about the employment in Y while being interviewed at X. But later when the interview result came, I immediately informed about my employment in Y by an official mail to X to which they rightly replied and asked for a relieving letter. Also I have disclosed all facts rightly about my previous employment while joining in X. Now as I have the relieving letter plus No Dues certificate from Y and that too I have submitted in X which they have accepted as well. Will the issue of non-disclosure at interview be a problem any more in future? Is it still a matter of suppression of facts? Is my employment liable to be cancelled because of that at any time in future?

Please note that I have a written disclosure regarding my employment at Y which I had mailed prior to joining at X just after interview results came where I have justified why I could not disclose the same during the interview. Is there anything to worry about now?
