The Danger Zone: Top Reasons Candidates Fail

Based on our database of Bitvavo interview outcomes, avoid these common traps:

Assuming direct exchange rates are always available
Using a single relational database without partitioning
Using recursion without depth limits on large datasets
Ignoring the need for deterministic ordering and consistency

Test Yourself: Real Bitvavo Questions

Three real prompts pulled from our database.

Type · architecture

Design a high-frequency order matching engine that can handle 50,000 requests per second with sub-millisecond latency.

Type · algorithm
