I applied through a staffing agency. I interviewed at Adyen (Bengaluru) in Aug 2024
Interview
The interview process started with an exploratory call with a 3rd party HR, followed by a Hackerrank test link(3 DS-Algo questions in 2.5 hrs). Followed by an HR interview(interest in the role and Adyen values), followed by 4 Face-to-face interviews(DS-Algo with a panel of 2 SSE/TLs, System Design with a panel of 2 SSE/TLs, Behavioral with a panel of 2 Engineering Managers, Leadership connect behavioural), followed by an interview debrief, followed by a team matching round with prospective manager, offer negotiation, followed by an offer roll-out.
Interview questions [1]
Question 1
Your contributions and impact of the existing role. Cultural fitment.
Adyen values.
All the tech questions were somehow related to Payments domain although they had similar(not exact) questions on Leetcode.
System design was also related to the Payment domain.
Hackerrank questions not only focussed on DS-Algo, But it also focussed on Java concepts and require practical understanding of OOP concepts.
first step is a call with HR to align on experience and expectations, then an online coding assessment on Hackerrank of which I believe you need to answer everything perfectly to go to the next step
Interview questions [1]
Question 1
HackerRank set of exercises split in sql and solve coding problems related to the industry
I applied through other source. I interviewed at Adyen in Feb 2026
Interview
Initial step was a 30 min screening call with someone from HR. They were very friendly. First time I didn't pass a screening call in years, make sure to study the 8 company values on their website beforehand.
I applied through a recruiter. I interviewed at Adyen (Madrid) in Nov 2025
Interview
Madrid: good technical process, but POOR communication and lack of closure after final interview
Pros:
* The recruitment process is technically good and well-structured in its early stages.
* The initial assessment consisted of a HackerRank technical evaluation with a programming exercise focused on performance, object-oriented design, and three SQL questions, which felt relevant and fair.
* This was followed by a technical interview discussing the assessment results and deeper system/design topics.
* I also had a hiring manager interview and a technical leadership interview, both of which were professional and engaging.
* Throughout most of the process, the recruiter was very responsive, usually replying within 48 hours.
Cons:
* After completing the final interview, communication abruptly stopped;
* I attempted multiple follow-ups via email and phone without receiving any response.
* Only after reaching out to one of the technical leaders I had interviewed with did the recruiter reply, stating she would call — but that call never happened, and communication stopped again.
* The lack of closure after reaching the final stage felt unprofessional and inconsistent with Adyen’s publicly stated values around transparency, ownership, and respect.
