Pros: The people: smart, empathetic, friendly; it is fun and motivating to work with leaders in their fields. Management: inspires faith in the direction they are taking the company, encourages stretching your comfort zone, is adaptive to circumstances, offers clear leadership while also being open to feedback. The work: challenging, ambitious projects. The tech: maintains several very active open source projects, including Apache Spark, and carefully adopts new technologies where it can provide long-term benefits. Growth trajectory: The company is doing really well financially, and you get to see how companies of this scale grow as fast as possible.

Cons: Can be stressful with lots of work to accomplish under sometimes strict timelines, especially for larger projects.

Pros: Good mix of open-source projects with a healthy community. Senior developers previously at larger companies. Market leaders and fast-growing. Strong leadership, some with an academic background.

Cons: Growing too fast, difficult to know everyone. Organization and processes evolving.

Pros: Smartest people you will meet. Plenty of opportunities.

Cons: Middle management wants to control, but has no idea what individual contributors (ICs) actually work on and what is required. The C-suite is absolutely amazing.
