Should I Share About An Existing Offer With The Recruiters

Hi,
I have an offer and the joining is on this thursday, but I am still searching for a better one. Let's say i got an interview scheduled before thursday, should I tell about the current offer and joining date to recruiter,if asked?
Regards,
Akshara

also, could someone tell me, how to delete threads once posted??

Dear Akshara,
Sharing information about an existing offer with the hiring team is a negotiation tool. Unless you want them to pace up the decision or offer you a greater package there is no reason why you should share it.
It can create a negative impact , if they already have a better offer for you.
Hence , request you to play your cards well.
Wishing you all the best !

Disclosing the other offer will not be in good taste.
The question is why have you come for this interview if you already have a confirmed offer.
Only reason the current job may be giving better package.
It also could be construed as a negotiating tool.
The company may think-person has not been selected and he is trying to negotiate.
In short,I would not disclose if I was in your place.
