Pros: Directly building something people use is great.

Cons: No career growth. I was in the same role 3 years after I was hired. "Speed wins" is used to justify sloppy work and never addressing the mountain of technical debt. New technologies, even those proven elsewhere in the industry, are resisted.

Pros: Smart coworkers. Flexible work schedule. Nice compensation for new grads. Free food/snacks.

Cons: Engineer turnover rate is high. Most senior engineers stay, but more SDE-I and SDE-II left during the past two years. We spend too much on recruiting senior people but do not try to solve the high turnover rate. Low salary increase, low RSU, and low bonus this year. If you were doing great, you get a 2% increase. Managers do not have the power to help your compensation if you are not satisfied with it. Higher management levels do not care about your dissatisfaction. Small teams with fewer engineers do not get higher-level management's attention, which means your compensation and opinions are not important to them.

Pros: Coworkers are very intelligent. Flexible work schedule. Standard perks: beer and wine at happy hour, foosball table and video games, food all the time. About to move into a giant new headquarters.

Cons: Engineering culture has become very fragmented. In the years since I started, the social community has faded, and it's harder to connect with engineers outside of your team. It's harder than it should be to switch teams, and hard to figure out how to advance your career.
