• Top of the market compensation (only very few companies can compete in the Netherlands).
• Good work-life balance; I can't recall a single time being forced to work overtime.
• Huge scale and interesting technologies.
• You have a lot of opportunities to make an impact with your work compared to what I know about other companies of such scale. It's not a startup anymore, but it's not an enterprise yet either.
• Lot of super-smart people working around you. Most of the high-rank technical folks are extremely supportive, as it's part of company culture, and otherwise they wouldn't be promoted/hired.
• Diversity of experience and background in people working in the same title.

• You'll have to spend at least some time working with not-so-sexy stuff like Perl. Nothing scary; trust me, if the money-making part of the business depends on some technology, the company finds ways to make it work reliably and look pretty despite its inherent limitations.

• As in any big company, the experience differs between teams and departments. However, you can change teams internally after working some time in the current one, so even if you're unlucky with your manager or with the work, it's fixable.

Keep up the work of retaining talent. It's visible and valued by the employees.

However, our HR brand is lacking. When I first joined, I thought it would be an awful experience and I'd need to endure a year and switch to something else, which could not be further from what I experienced in reality. Aligning the expectations of external hires with the reality would benefit the company to a great extent.
