You'll get a lot of experience and a lot to talk about in next jobs
Pros
True Media will trust you with a lot quickly. They'll pile a lot on your plate and they don't do any hand holding. This will give you lots of experience, fairly quickly. There are also some really fun people who work there, a lot of young people. If you're a younger person, you'll always have someone to go to lunch with or hang out with on the weekends. Vacation policy and flex time is solid. They're not insane with it, but 10 days of vacation (prorated your first year of course), some flex time, and 10 sick days could be way worse.
Cons
Management was out of touch with problems or just didn't care. Things changed too often and things were always disorganized. Sometimes we'd have meetings where management would tell us one thing and then another manager would tell us something totally different. If we asked about it it was clear they hadn't thought anything all the way through. Pay was low, don't expect to every make a down payment on a house or even make a car payment if you have even a little bit of a student loan. The CEO doesn't understand student loans and doesn't believe in adjusting pay to compensate for the student debt almost everyone has. They also expect you to work as much as possible for your small salary. You'll frequently hear "I never said this was a 40 hour a week job" from the CEO. Also, if you're a woman, you have to fight to make as much as your male counterparts are offered immediately. There's tons of turnover. Expect someone on your team changing at least twice a year. They consistently say they're growing, yeah, well, they're hiring to make up for all the loss. It gets really exhausting constantly training and retraining new people because you change team members all the time. Oh, they also ask their interns to leave them good reviews on Glassdoor.
