Adyen Software Developer interview questions

Phone recruiter screen with honestly one of the best recruiters I've encountered Initially completed a hackerank that covered pyspark fundamentals. 4 separate interviews with teams across time zones. One was local team, one was Amsterdam team, one was with SVP and one was with manager.

Had a call with a recruiter then behavioral interview where you need to know Adyen formula. Then they will give you technical home task for 3 hours. Then tehcnical round where you talk about your solution(no coding) and systed design. After that I was rejected and recruiter didn't provide a written feedback. I'm sure I was rejected because of the indian guy at the interviews. The whole process was very biased.
