DE Shaw referral query

I recently got a referral for a job posting at DE Shaw at Human capital, and the guy who referred me said this "I’ve referred you for both roles (and all other roles within Human Capital). You should be getting a call from recruiters if you are shortlisted."

Usually, you get a mail that you have been referred and apply to this job via this link, but I have yet received any mail yet regarding any referral, which is odd. I don't know how the referral system works at De Shaw.. Do you guys think that i should apply for the job directly? just wait for the referral, i am confused, please help
