Why do recruiters ghost after interviews ?

Just trying to understand what could be the reasons behind this?

In the past couple of months I have given multiple interviews where the interviewer said that they are good to go for the next round as the interview went well but the recruiter keeps ghosting. I am not sure where I am going wrong?

I gave my 3rd round of interview on last Friday and it went very well. I was told it was the last round and I was looking forward for an offer. But recruiter is telling me from the past 3 days that she hasn't received any feedback still and she should receive it soon ( the guy who took my interview was from US team). Is she bluffing?

Ghosted by recruiter after they gave verbal acceptance 10 days ago. One of my other offers expired during this time and now the recruiters are not replying to my emails at all. Have included the hiring manager in the emails as well. But no one is responding.

Today I got a call from the HR team that I've been put on PIP. I have been on Bench for 2 months and they are doing it for Cost cutting. Furthermore they asked me to get a project in 2 months otherwise I have to self resign. My doubt is if they forced me to resign after 2 months in case I didn't get any interview calls, Will they give me notice period (3 months) salary???

So Flipkart will be doing performance based layoffs. I have been placed on PIP. How should I proceed considering I don't have any other offers and not much experience either. 1. Resign immediately. 2. Do the PIP completely and then see if I pass or not? I am not in a good financial position currently.

I had a recent experience of having an interview with this MNC and getting negotiation calls,and I was willing to settle near their offer, just because the office was very nearby and then suddenly I got ghosted. I was not even actively looking for a job and 6 rounds of conversation and a month later I got ghosted. Why HR's don't give a black and white answers.

I’m interviewing with one of the FAANG company, the interview process completed last week and recruiter have ghosted me. What are some valid reasons for ghosting? They could have just acknowledged and said will get back with more information when they have, instead of ghosting. Would you like to share some of your ghosting stories. I’m really anxious to know about the outcome that’s why this rant.
