Pros
Adyen apparently had nice perks when COVID was not around. It was possible to visit other offices around the world, join massive company events and parties, and meet a lot of other fellow expats. Work-life balance is decent, and no one is going to require your presence at a fixed time frame.
Cons
As many other software engineers have mentioned, it is a pain to work as a developer. Every time you need to pull software changes, the IDE is going to re-index the entire code base and you need to re-deploy huge chunks of code even if you changed a single line only, both steps can take up to 40 minutes of your day. When you push your changes, it is very common to wait 2+ hours for the CI/CD pipeline to finish. But the biggest problem of all is how the leadership undermines any initiative to change that scenario, and maintain the bomb of spaghetti code lines that we have . We have a saying that reads "We embrace new technology when it has clear benefits", which it is obviously not the case. For example: people have to fight hard to be allowed to use Mockito. That is correct. Mockito: the simplest mocking framework out there, is not suitable for Adyen, but it's suitable for everyone else, God knows why. And that is only one example out of many others that I could mention, but I will refrain from scaring you any more.
