Mature: respects others’ opinions, beliefs, and culture; listens to ideas, shares thoughts, and works independently and together to contribute insights to the company’s leaders.

Forthright: speaks with conviction; argues based on understanding, respectfully

Inquisitive: seeks deeper explanations of how systems work, not the surface-level description of the actors involved; goes beyond “stick-fetching” to connect the unconnected.

Honest: knows what’s right, what’s legal, what’s appropriate; acts accordingly.
