I currently hold an offer from an employer. I had told my new employer that my official notice period is 2 months. But my actual notice period is just 30 days so that I can have more time to think and also try for better opportunities in this time. Is it ok? Will this be a problem for me when I join? My company does not mention the resignation date in the release/service letter. Just the releasing date. Is there any other ways my new employer can learn this? Or do they really care? I dont want to be in trouble on my first day. Thanks in advance
Will they find out? It's possible. If they look at your relieving letter or background check and see that your last day was only a month after your offer and a month before you started, that means that either your notice period was only 30 days or you resigned a month before you got an offer.
Will it affect you? Who knows. In all likelihood, these details will only go to HR, and the hiring manager who negotiated your start date won't see it. Even if they did, they may not notice or care. If I saw that, I would probably make a mental note of the discrepancy but not say anything about it. Other people may be more upset and confront you on it. It all depends on the manager.
Now, you really shouldn't have lied in the first place. You should have just told them you would be available to start work 2 months after you receive your offer - this mentions nothing of the notice period. If you're pressed on it you can always explain that you want to take a month of to travel/visit family/whatever. There's nothing wrong with that, and most employers won't try to get you to start earlier (at least in the US).
