Adyen Data Engineer interview typically runs 4 rounds: recruiter interview, first interview, team interview, and a HackerRank test. It took about a few weeks and felt uneven, with a light early screening before the coding check.

Our candidates report that Adyen’s Data Engineer process is less about theatrical difficulty and more about whether you can work cleanly with real data structures. The standout signal is the coding work: the PySpark portion was described as straightforward on the surface, but join logic and dataframe handling were where mistakes could quietly sink an otherwise solid attempt. That tells us the bar here is not “can you memorize Spark APIs,” but “can you manipulate data correctly without introducing subtle bugs.”
A recurring theme is that the company seems to value engineers who can move between implementation and product-minded collaboration. One candidate noted behavioral prompts around being collaborative to solve a problem and sharing a project that aligned with company values, which suggests they are looking for people who can explain tradeoffs and work well across teams, not just write code in isolation. We also saw that the recruiter conversation felt light and uneven, so the real evaluation appears to happen once the process reaches hands-on technical work.
The non-obvious takeaway is that Adyen seems to reward precision over complexity. The Python task involved JSON serialization/deserialization with existing and new classes, which is the kind of exercise that exposes whether someone reads requirements carefully and preserves structure. In other words, candidates who do best here are usually the ones who are methodical, comfortable with practical data transformations, and attentive to edge cases that can break a pipeline in production.

The part that stood out most to me was that the process felt a bit uneven from the start. The recruiter interview was very light and honestly not that useful as an evaluation, because I wasn’t even asked to introduce myself properly. Instead, I got a question about my recent achievements, along with some instructions sent ahead of time that didn’t really help much in the actual conversation. After that, the process moved into a first interview and then a team interview, and only then they sent a HackerRank test.
That test was the most concrete part of the process. It was split roughly 60% PySpark and 40% Python. The PySpark section was mostly dataset manipulation using a template and different methods, and it was fairly easy if you were comfortable with the basics, but you had to be careful about joining the dataframes the right way. The Python part asked me to complete a JSON serialization/deserialization task using existing classes and adding a few new ones. On top of the technical side, there were also behavioral questions about a time I had to be collaborative to solve a problem and an example of a project that aligned with their values.
Overall, the process felt more like a mix of light behavioral screening and a practical coding check than a deep technical interview. I didn’t get an offer, and the main takeaway for me was that it helps to be ready for a fairly simple but detail-sensitive PySpark exercise, especially around joins, plus a Python task involving JSON and classes.
Prep tip from this candidate
Be ready for a HackerRank-style assessment that is mostly PySpark dataset manipulation plus a smaller Python JSON serialization/deserialization task. In the PySpark part, pay extra attention to how you join dataframes, since that was the main place where it could go wrong.

Synthesized from candidate reports. Individual experiences may vary.
An initial recruiter conversation that was described as fairly light and not very evaluative. The candidate was asked about recent achievements and received some instructions ahead of time, but did not even get a full self-introduction prompt.
A first interview followed the recruiter screen, likely serving as an early behavioral and fit check. Based on the experience, this stage was part of a broader sequence that included collaborative and values-based questions.
The candidate then met with the team before receiving the coding assessment. This round appears to have included behavioral discussion, including examples of collaboration and projects aligned with Adyen’s values.
A practical coding assessment sent after the interviews, split roughly 60% PySpark and 40% Python. The PySpark portion focused on dataset manipulation and joins using a template, while the Python portion involved JSON serialization/deserialization with existing and new classes.
