Pros
Excellent pay: including stock, 10% discounted ESPP for up to 15% of your salary, 50% match on 401(k). Unlimited vacation time, including company shut down from Christmas to new years and 1 week shut down for 4th of July. Flexible hours: no one care when you come in/out or work from home as long as you get things done. Good work/life balance. The company has programs that encourage happiness, health and well being, like on-site gym and $2000 annual wellness allowance, monthly indays. Fair performance evaluation and room for growth. Plenty of tech talks for you to improve yourself. LinkedIn's titles are a little inflated in comparison with other companies (e.g. other companies take longer to get to senior), so it'd be to your advantage when jumping to another company
Kontras
Uncertainty around Microsoft acquisition. Some company politics, though as an individual contributor I'm somewhat shielded from it. Instead of building new innovative products and cut edge technology, there are many technical debt and migrations with technology that engineers are not very excited or proud of.
