Le processus a pris 2 mois. J'ai passé un entretien chez Adyen (Amsterdam) en mai 2022
Entretien
1. Initial discussion with 2 engineering teammates. Mostly only moitivation and culture fit;
2. Home take code testing.
3. Review and discussion on the code testing submission.
4. Interview feedback by HR.
5. 2 rounds of culture fit interviews(which they called board interview/formula interview)
Questions d'entretien [1]
Question 1
The main technical interview are in step 3. A lot of why/what if/how questions were asked.
For example: the code testing is consisted of 1 SQL task, 1 algorithm related with in memory cache and searching, 1 skeloton project.
For task 2:
Why you design/choose the solution(my case is Map)?
What is the time and space complexity of the algorithm?
Any more solution you can think of?
What is the benefit of xxx(a certain kind of technique, my case is in memory cache)?
For task 1:
If the requirement changed to xxx, how will you handle the case? My case is when joining 2 tables how to find records that are not matched.
How to improve SQL performance? What can cause slow query? Notice they will ask if any case of slow update/delete.
Is creating the more index the better?
For task 3:
Again why you design/choose the solution(my case is AtomicLong)?
Also being asked to find bugs in the code submission.
Also question about concurrent call.
So looks like performance is one of their major concern

Entretien
I applied as a java developer (graduate program).
There were 5-6 rounds which consumed a lot of time (If you pass one round, then you'll be moved forward).
HR screen > introductory session with one senior dev (introduce yourself, why you're interested in Adyen) > Hackkerank > Code review with one tech lead and one senior > so on..
I failed at code review, they asked a lot of deep question to determine whether you really understand java.
It was good and well organized. First they gave an coding exam. Once I had finished it, next interview went around with my coding exam. Asked detailed questions about what I've dine with the exam etc.
Questions d'entretien [1]
Question 1
Basic Java knowledge and computer science fundamentals

I have been setup with first interview with a recruitment person. He has asked only a very few questions such as why are you changing the job. After that I got rejection email. I could not understand on what basis are they filter a software developer after a brief chat.
