Pros
Most of the engineers are quite enjoyable to work with. All talented and helpful. I am still friends with many of the people I worked with while there. OT was also great for continual learning. Supporting the team with books and conferences.
Kontras
The business structure and hierarchy is larger than needed and rarely hears things from the bottom. OT also chose to close a branch office (the one I worked at) with no real investigation into the work that we did. Then proceeded to wait until the last week of our employment to actually care about transition. (At which point they panicked) The conglomerate (Priceline Group owns OpenTable, each with their own CEOs), didn't work. It might be a failure to communicate, but having two CEOs on top of a board and shareholders felt like it stifled innovation, but having too many layers of approval and blame caused nothing to happen.
