Urgent Suggestion required.pls

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?

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??

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?

I already have an offer with 70% hike and I am getting 30 to 40% more hike as a counter from different organisations. I would like to know if it is good to accept a counter offer? Because the first organisation was waiting for the last 3 months for me and I am not getting how to say no all of a sudden for joining. Should I reject a counter offer? Pls pls suggest me

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?

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.

I am on my 3 months notice period, but since the time I put my papers I have been contacted by a senior stakeholder, my previous and current vp suggesting me to stay saying they'll try their best Is it something normal, should I reconsider? The other firm has been waiting since past 2 months Got a hike of 45%, please suggest as confused 2.5 yoe
