Not everybody thrives at Adyen, and especially if you're more comfortable with a clear, templated growth path supported by work instructions and formal process, you are likely to have difficulties adjusting.
I'd also say that if you think back to your studies and think about group work and remember that you weren't the one or two people on your team doing all the work, Adyen might not be a fit.
While other people in your team will be looking out to support you in your work/life balance, it's possible to over-commit, with consequences for your personal and family life. This isn't as well managed as a lot of other things at Adyen, and you do need to look out for yourself to some extent, although there's been significant improvements recently in this area.
Adyen's largest office is in Amsterdam. It has some more large offices in major markets or international hubs, and these are the locations where a lot of the networking and decision-making take place. This will sometimes have impact on your work day and your home life, even if you work from Amsterdam, since the colleagues and customers you'll be working with may be many timezones away, and the practice of working intensively together using calls is built into the culture and practices.
"Own your own career" has been proven to be tough for some new hires, and the advice that I'll give is to focus on gaining mastery in your area, a good mentoring network and keeping an eye open for opportunities to grow, since the best opportunities won't be handed to you on a plate.
Tech as a whole has suffered from a lack of diversity, and while a lot of progress has been made there's still a lot more to do. At Adyen, diversity and inclusion is a high priority, and if you're a new hire from an under-represented group in some teams and countries you might find yourself doing some gentle path-finder work, which is not for everybody.
Many real decisions are made mostly - but not always - bottom-up. If you're new and want to make a big impact, simply pitching your ideas to management typically doesn't work. If there's a smell of CV-driven priorities, without a real game-changing business impact, you might be SOOL. Change and impact works by building up a network who support your ideas and who will help prototype what you want to achieve and pitch with you across the organization. This can take some time and practice.
