I applied online. The process took 1 day.

Applied for the Amsterdam office via LinkedIn and received a prompt response from the recruiter. The interview process started with an introductory call with the recruiter, followed by a hiring manager screening, two rounds of technical interviews, and finally a so-called “bar raiser” round.

The recruiter call was mostly housekeeping questions but delivered with an unexpectedly intense tone. The hiring manager round, however, was the worst interview I’ve ever had with a manager. He attempted to dive into technical details, asking a series of unclear and sometimes absurd questions about my previous projects.

At the end, he asked me to implement a simple yet confusing logic related to processing user refunds. The conditions he provided were contradictory, so I asked for clarification and tried to confirm the expected inputs and outputs. He was reluctant to explain anything, but I still implemented the logic based on the requirements he gave. When we tested different inputs and outputs, even he seemed unsure about what the correct results should be in several cases.

Implement a safeguard logic that ensures the seller’s wallet balance cannot fall into a negative state.
