Adyen Data Analyst interview questions

Was scouted by internal recruiter. Followed up with hacker rank assessment and review of the code with peers. The last part was interactive discussion about my solution with 2 Adyen employees who worked in the relevant team.

Interviewed with Adyen for almost a month, went through 4 rounds of interviews (including an hour-long case study). Before the final round they told me they would not be moving forward due to a surface level conversation. Taking an entry level position through 5+ rounds to let them go after everything seemed a bit ridiculous and harsh to me. I probably spent 20+ hours researching, studying and understanding the company to interview well. I was told my case study was excellent and they moved forward with me after but during the last round (after 3 previous rounds) they thought it was "too surface level."
