Pros
I worked with many talented people over my time at Priceline and made life-long friends. Great culture in the NY office with lots of parties and events for different holidays. The CEO tries to be transparent and has regular CEO updates which can be more informative and interesting than other companies I've worked at. Have a lot of internal tools to support your work, especially on the data side. Decent benefits and PTO policy.
Cons
You have to tip toe around leadership. Lots of politics. No training for future leaders and managers. You only get management training once you become a manager so people in a "lead" position get no training on mentoring or coaching. Too many meetings. People would set up meetings to decide what they were going to meet about. I had to block off my calendar in 1–2 hour increments to make it look like my schedule was full in order to get a day of work in with no meetings. There are some toxic leaders from c-suite down to managers. People were hired without being interviewed because they had worked previously with a c-suite employee. There was an entire team that was having difficulty with their manager and HR did nothing about it and put the blame back on the ICs. ICs are never asked to review or give feedback on their manager. Design team was extremely under-resourced for years. Some teams had 1 designer to 3–4 PMs. The designers had to rush through their work and many times had to forgo research to move quickly. The design team has had a very high turnover rate and in 2019 about 6 designers left in a 6 month period. Design has felt under valued at Priceline for a very long time.
