In terms of negatives, nothing stands out as an obvious negative. There are concerns though, that relate to different groups and can get in the way of you enjoying your job.
First and foremost, I think you need to take a long and hard look at who your manager is going to be and what his or her managing style is going to be like prior to taking a job at TripAdvisor. If you know people that work at TripAdvisor, fully make use of that resource and try to understand as much about the group you are joining as you can. I believe you are in charge of managing your own career and the reason there are some mixed experiences at TripAdvisor is because different managers and different groups operate differently. Product is very different from Engineering which is in turn different from Mobile or New Initiatives. Some bosses are more hands on and others give you a bit more rope.
A second issue is career advancement. TripAdvisor is rapidly growing, which can be done in many different ways. Some of it has clearly been through acquiring other internet companies into the TripAdvisor Media Group umbrella, which, for the most part, will have no affect on your career. The second, which can be questionable is the hiring of middle/upper level management that tends to create new layers of the pyramid that didn't previously exist. How that would affect your own career progression is unclear at this point. I think it is critically important to have an open conversation with your manager about career progression before joining, and maintain that dialogue over the duration of your career.
Lastly, there is the issue of collaboration between groups and overarching oversight. I think as a whole, we do a very good job of pushing out new ideas and distributing responsibility between the groups. However, different groups sometimes have diametrically opposed goals which puts added pressure on upper management to determine the overall direction of the company. I think there could be better communication of the direction we want to take TripAdvisor over the next few years and more collaborative brainstorming that helped make people feel invested in the company as a whole, and not just the group we work in. For example, its easy for a group to feel that their only concern is to increase the # of subscriptions or referrals to a new product, but not enough work is done to communicate how your individual goals tie into the company's goals and determining where collaboration between groups can further progress for everyone.
