About You

You're not like everyone else.

You bring a unique perspective to the table. Transparency tops your list of values. Your smarts and creativity are off the charts, matched only by your humility. You want to collaborate with a team of diverse talent. You proactively contribute to a culture of respect and inclusion.

You enjoy a challenge.

Inquisitive and focused, you see every challenge as an opportunity. You're ambitious and unafraid to make mistakes because you learn from them and bounce back quickly. You don't stop until you get it right. "Impossible" isn't in your vocabulary. You're more interested in creating the future than waiting for it.

You love to listen.

You start every interaction from a place of listening and seeking to understand. You're culturally connected. You remember your first concert. You can readily recommend a binge-worthy show on Netflix, Hulu or HBO. You can't sit in traffic without a great audiobook, podcast or album. You can make a killer playlist. Your idea of a good weekend includes watching a movie or playing a video game.
