Will PWC acceleration centers provide offer with 90days notice period?

Please let me know if anybody got an offer from pwc acceleration centers with 90days notice period. Interviews are done 2months ago and now I situations changed in my current project. Now I think our project will not allow for less than 90days. Need inputs.

Also can I ask pwc to give me offer for 1st June as I may receive my annual bonus on may month end before switching. If not I will loose entire annual bonus - my one year hardwork if I have to leave earlier than may end as per policy. It will be hardly 1 week difference with 90days notice period.
