Working with really smart, knowledgeable, pleasant people.
The benefits options are pretty varied for a company our size.
They are highly collaborative and open to cross-team cooperation and communication.
The individual people's attitudes and approaches to the culture. TR is great at hiring people that then shoulder the responsibility for the culture and environment when leadership policies are lacking.
They try to be as transparent as possible about business decisions and the state of the company at a given time. Individual leaders are very accessible by the rest of the company.
Getting to interview with most of the department I'd be working in. I got a really strong sense of who my coworkers would be and what they're like, which was very influential for me.
