01
No junior sourcers
Every first call is made by a partner. It is slower and it is the whole point.
02
We publish the funnel
Clients see who we called and who said no, every Friday, for the whole search.
03
We say no
We turn down about a third of the briefs we are offered, and we explain why.
04
Candidates first
No CV leaves this office without the candidate’s written permission. Ever.
