I applied through an employee referral. The process took 4 weeks.

The HR was answering emails quite fast and got to the final technical interview; however, the HR didn't send me any update regarding my application, and after asking about it, I found out that I won't continue the process. My experience was that when a candidate passes the interview, they send you the email quite fast, but if you didn't pass, you're being ghosted if you don't approach them first. I get it, but it would still be nice to inform candidates when they don't pass as well, rather than keeping them waiting.

Got questions about Adyen's formula and technical ones regarding ML models and architecture.
