• Super smart colleagues.
• Very relaxed work-life balance: you can go home at 17:00 and don't think about work until the next day.
• The huge scale to work with.
• Challenging technical problems.
• Qualified top management which knows what it wants.
• Data-driven culture: if you have good data to support the change, you are free to implement it. If you have good reasoning, you can also "sell" your change to the management and make organizational changes.
• A lot of things are imperfect but in motion to determine how to make them better, and the company seems to care to make things better.
• People are very helpful, and we have lots of amazing communities with people supporting each other and discussing common interests. In Amsterdam, if you want, you can live without having friends outside of work, and you would have a lot of communication with a diverse range of people nonetheless.

The promotion process is one of the imperfect things that is in motion at the time of writing, which means that you don't know for sure what exactly will be the criteria on the next promotion cycle. However, hard-working people with lots of impact get recognized and promoted regardless of current rules changes, and this only affects someone who is in the grey area and doesn't have a solid case for promotion.

Keep up the good work and keep encouraging communications between different management levels.
