Adyen Software Engineer candidates describe an assessment-led process in which the submitted work can become the center of the next conversation. One candidate reported four rounds including an online assessment, followed by a discussion of the submission. Other candidates likewise describe a HackerRank assessment before engineers review their code, sometimes asking why a particular algorithm or data structure was chosen and how it could be improved.
Reported assessments have included SQL, object-oriented Java, algorithms, data structures, and a rate-limiting problem. The recurring technical theme is concurrency in Java. One candidate said most of the follow-up discussion concerned concurrency and multithreading, including the time complexity of the submitted solution and alternative data structures that could improve it. Prepare to explain how your implementation behaves under concurrent use rather than merely presenting working code.
Later stages vary. Candidates report system design, team or hiring-manager discussions, behavioral questions about work history and automation, and leadership conversations. One candidate reached a technical discussion without receiving the expected system-design questions, while other accounts describe system design as part of the interview. Keep preparation anchored in your submitted work, but also have concise examples ready about challenging projects, automating repetitive work, collaborating with others, and communicating technical decisions directly.

Real interview reports from people who went through the Adyen process.
There were four rounds in total, including an online assessment. After the online assessment, there was a discussion of my submission. This round could include system design, although I was not asked system-design questions. I was rejected after the discussion round.
Questions asked: The online assessment had three SQL questions, a Java banking-system question requiring multiple interfaces, and a data-structures-and-algorithms question about rate limiting with a concurrency focus. In the discussion, they asked about time complexity and alternative data structures to optimize my solution. The conversation focused mostly on Java concurrency and multithreading rather than SQL.
Prep tip from this candidate
Practice explaining Java concurrency choices, time complexity, and alternative data structures for your submitted solution; the assessment may combine SQL, object-oriented Java, and rate-limiting work.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an initial recruiter or HR conversation covering background, the role, expectations, motivation, and sometimes salary expectations. Treat it as evaluative and answer directly; one candidate said the recruiter screen used a structured format.
Candidates report HackerRank-style or take-home assessments. Reported content varies from SQL and a Java interface-design problem to algorithms, data structures, or practical payment logic. One recent account included a rate-limiting question with a concurrency focus.
Several candidates report engineers reviewing the assessment solution. Be ready to explain algorithm choice, time complexity, alternative data structures, implementation decisions, and revisions. Some reports say this conversation also shifts into behavioral questions.
Candidates who progressed report differing later routes: system design, team or hiring-manager discussion, behavioral interviews, and leadership conversations. System-design topics may involve payment services, while behavioral prompts may ask about challenging projects, automation, or disagreement with a manager.
