Pros
The location in downtown Bellevue is good, convenient bus access, but the thing that gets you coming into work is the people. There is a lot of excellent people that are there, who care, have a strong work ethic and go the extra mile to help you out. Some teams/groups have good leadership who care.
Cons
Work life balance, recognition, job growth, training and mid level management are all serious cons. Many groups expect long hours and end up being in an on-call all the time. If you get tired of 7 day weeks and consistent 60-90+ hour weeks and say something you it is remembered when review time comes. When you kill yourself for them you are asked to do it every day, with no "good job" or "thanks." Every year I was at Expedia, there was always a lot of training budget and folks said "no one takes training...take some training" but when you signed up for it or requested it it was denied or cancelled by your boss. People routinely get stepped on by those trying to climb the ladder. I watched a lot of really good people leave or get laid off and those who stayed had to pick up the slack. Management takes credit for things that they didn't do. One manager will get the highest rating, while his whole team gets low reviews. Reorgs every 6 months.
