How blacklisting happens

Once we accept multiple offers, how and when should be reject them before joining in a good way? And do companies blacklist if we reject the offer after accepting?

One of my friends recently received a counter offer from one of the MNC company.. So if the company offers a counter offer and After that he still doesn't join..then in that case is there any concern about the risk of being blacklisted as he might not choose to join the company even after accepting their counter offer. Is there a possibility of affecting his future opportunities with the same company? Do they black list for rejecting their counter offer?

I recently received a counter offer from one of the big 4 company.. I had initially decided not to join. I am reconsidering my decision and would appreciate your advice on the potential consequences. Specifically, I am concerned about the risk of being blacklisted or facing negative if I choose not to join the company even after accepting their counter offer.

Hey Guys! I am new to the corporate world and am not familiar with all the nuances, is it okay that you change your mind during the notice period and decline an offer post accepting it from another org?

This could be a rookie question, but what exactly are the implications of accepting the official offer letter and then not joining the company? Any legal issues can come? If not, then what's the point of all those formalities- these guys even capture the IP address, signature etc when the offer is accepted. Why all that fuss? Also, when exactly does an individual become an actual employee of a company? I mean, at what point of the on boarding procedure do I legally become an employee?

Sorry for being a pussy but I'm very new to this. So I accepted an offer from a company and did the BGC docs and all. 2 month later, now I have a better offer that I want to join. I'm sure I don't want to join the first company. Was gonna call the HR now, but what do I say??

I got an offer, I knew the role was not great but still went ahead to see if pay would be better (75% up). But I still would like to try for a better role and not accept this. I need your suggestion on how to do this, so that I won't be blacklisted for future opportunities of the offered company.

How common it is to decline an accepted offer? What are the repurcsuions attached to it? Have you guys ever done it? How should I communicate to the company? What should I write in email?
