Pros
Some of the smartest, nicest, loveliest people I have ever worked with are at Twitter. Offices are nice, perks are on par with similar companies. Decent pay when I was hired, though not sure what it is today. The platform is still a pillar in modern media, especially in sports, politics and entertainment. Though this allure is also dissipating.
Cons
Absolute mess from a strategic and managerial perspective, across all departments and areas. Decisions made with ego rather than strategy in mind and with opinion rather than insight, which leads to very poor career advancement opportunities. Developing an echo chamber culture and mentality. With atrocious middle management and lack of direction, you see people and teams turning on each other more and more. High turnover and constant departures at all levels. Embarrassingly poor diversity across race, gender and age. Morale could not be any lower.
