Other

29 people work in this department. Hard to read from the outside: use a first exchange to map who does what before pushing an offer.

General Management

A team of 22 people. General management thinks in strategic priorities: link your value proposition to one of theirs or you will not get a reply.

Operations

This department counts 9 people. Process efficiency and cost control are the angles that resonate with these decision makers.

HR

6 people work in this department. HR teams are heavily solicited by vendors: differentiate with proof, references and numbers rather than promises.
