Pros
LM is easily the best job I've had (been working in tech for 10 years) and, as the review title says, I'm going to have a tough time if I ever have to find another one. Best things: lots of really smart, nice folks without big egos (data always wins over opinions); very flexible work schedules (for roles that don't depend on a set schedule) and vacation policy; great work office environment (I often choose it over working from home because it's so much fun). There's a kegerator, lots of great snacks (healthy and not-so-much), and lots of opportunities for outdoor activities (beach parties, etc). The office location is great, as it's right around the corner from State St and all sorts of lunchtime delights. The company is well-focused (they know what they're about and don't take knee-jerk detours into other areas), which makes the work itself more fun and easier to collaborate on. I recommend a career at LM to my favorite people with no hesitation.
Cons
None for me so far.
