Pros
This is truly a company that wants to do well, and has done a great job so far of surpassing the competition in becoming a stand out in the ad-tech space... just look at the stock gains. You'll learn a lot real fast so as long as you're able to stand on your own two feet and live and breathe the culture. It's a great resume addition.
Cons
TTD is a culture first company; if you don't drink the kool-aid you won't last long and you will not enjoy yourself. If you aren't "one of the guys" then you won't grow a career here. Don't believe everything management and the executive leadership tell you. Just read previous reviews (not the blatantly obvious positive ones "People Ops" has employees write) and you'll see the true colors of the company. Gossip is real and team cliques are all over the place. The pay is poor for what you can make elsewhere.
