Adyen Software Engineer interview questions

1 Phone Interview 2 Technical task 3 Phone interview about technical task 4 Final round of interviews at the headquarters (3 in a row) They took me to Amsterdam for the 4th stage, the final round of interviews. The 1st interviewer was completely lost, he asked his partner what they were supposed to do and he thought I was on the 3rd stage. He was about to review the code task, but then realized the mistake and started making questions. He clearly didn't prepare the interview. After that, instead of getting into the 2nd interview the recruiter came to the room and told me that I didn't pass the 1st and I wouldn't have the next interviews to not "waste people's time". The reason? "The interviewer was expecting more detail in your answers". He basically came unprepared, made generic questions and then complained about the lack of detail in my answers. I've never seen an interview round being aborted like that even in the most picky innovation companies. Which kind of company brings a candidate to the last stage and dismiss him abruptly because of ONE opinion of an unprepared interviewer? Long process, unfair, embarrassing and huge waste of time. And needless to say that the recruiter promised a detailed feedback that never came.

Utmost nonsensical application process ever. You are asked to complete a few tests (~3h) that are quite easy for everyone with decent programming skills. After that, you are invited for an interview in which you discuss what you did with two interviewers that not even educated in the field of software engineering. You can be outstanding and exactly what they want in terms of skills and have a great, positive and energetic character and even then they might reject your application based on one question at the end of a 45 minute interview with which they assume an entire character. The question is not even one that reflects a character or a set of skills. Their justification after for the rejection is basically a bunch of wild unjustified assumptions about your character that they felt were reflected in the interview. Even though you might be perfect for the job, a wild guess about your character is enough for them to reject the entire application process. What a joke. Just looking for a sec though the CV or just asking would prove them otherwise but no, let's just go with our wild instinct
