Q.2) I recently asked some contacts at Bain Capability Network for a referral but none of them could find the roles listed on the internal referral portal. Why is that ?
Q.1) Is there a cooling period at Bain Capability Network & Mckinsey if I get rejected at the resume screening Stage but I never received a formal rejection email. Should I continue applying for other CoE's ?
Q1, typical cooling period of around 12 to 18 months after a formal rejection, but if you never received a formal rejection email it is a grey area. Could be that system has logged you as rejected for that specific role even without the email. You can still apply to other CoEs but potentially use a different office or capability area to avoid getting auto-screened out. Worth reaching out to a recruiter directly to clarify.
Q2, a few possible reasons. Potentially posting could have been pulled or paused without being taken off the public site. It could also be a role being filled through a specific recruiter pipeline rather than open referrals. Best to ask your contacts to check directly with the recruiting team or the hiring manager if they know them.
Good luck !
