Pros
HookLogic is becoming a real heavy-hitter in the digital ad space. The company has grown quite a bit since I started there a year ago and shows no signs of slowing down, which can only mean more career opportunities and growth down the road. The office environment is fun, casual and -- as has been my experience -- as long as you get your work done, nobody micromanages.
Cons
The Ann Arbor office can be a bit cliquey. This isn't a deal breaker for me, as I tend to keep my work life and my social life separate, but if you aren't in one of the inner circles, don't expect to get invited to happy hours unless either a) it's a company sponsored event, or b) you find someone who knows and ask them what the plan is. I can see why some of the negative reviews described the office as a "good old boys club," but I would NOT go as far as to say it's like working for a fraternity and getting paid to be hazed, as one of the negative reviews pointed out. At least not on my team.
