Pros: Great environment and culture. Company fosters individual growth. Lots of perks and morale events. Z-speaker series! We've had Arianna Huffington and Vicente Fox come give talks, for example. Transparency. Free snacks, free lunches at the end of the month and on days where there are events. Great work/life balance. Fair, competitive compensation for engineers. Engineering teams are committed to moving forward and fixing issues with both code and process, rather than band-aiding things.

Cons: Growing rapidly, which is great, but things do change a lot. Sometimes it takes a while to catch up to them. Snacks rotate too frequently. Don't get too attached to anything, because it might be gone the next month. Lots of domain knowledge is required to move through the codebase very effectively. This can be a little intimidating for new hires and can extend ramp-up to several months if your work touches multiple areas on the site. Don't feel intimidated to ask someone, though, because we've all been through it, fully understand, and are working to improve it.

Pros: - Ridiculously fast growth and fantastic culture. - Hack week is probably the most fun I've had in my software dev career. - The people around me are the best balance of passionate, fun, yet professional that I've worked with in the industry. - There's always a lot of interesting work to do and problems to solve, but I'm still able to consistently work 40-45 hours a week.

Cons: Not quite elite compensation package. The company seems to be trying to hire top candidates, but offered a smaller comp package than what I was offered from Twitter and Facebook, and no free (daily) meals or parking.

Pros: Great engineering culture. Good work-life balance. Smart co-workers and awesome management.

Cons: I cannot think of any cons.
