Pros: Nice community feel for an office of this size. Everyone is treated as an equal. Plenty of perks, benefits, and company events. Opportunity for travel (depending on role). Very considerate management, open to new ideas, and they always listen if you have something important to say. Loads of highly-skilled colleagues to learn from. State-of-the-art equipment. Very comfortable work environment (best in my 17-job career). Most work environments look like a sweatshop by comparison.

Cons: You have to watch some training videos every now and again.

Pros: Clever people, solving problems that make the world a better place.

Cons: It's a relatively large company. It has problems that affect all large companies.

Pros: Flexible working environment and good team support.

Cons: Very large companies can result in duplication of projects and a certain amount of bureaucracy.
