Testing Interview Questions | Qdrant | NextRound

1How would you write a fast, reliable integration test for code that depends on Qdrant, without hitting a shared production instance?Intermediate

2What is Qdrant's in-memory (:memory:) mode useful for in a testing context, and what are its limitations?Intermediate

3How would you test that a filter-plus-vector-search feature behaves correctly, beyond just checking that it returns some results?Intermediate

4What would you include in a regression test suite to catch an accidental change in distance metric or embedding model during a refactor?Advanced

5What metrics matter most when benchmarking a Qdrant deployment for a production launch?Advanced

6How would you construct a ground-truth dataset to measure recall accurately when benchmarking ANN parameters?Advanced

7Why is it important to load-test with realistic filter selectivity and payload sizes rather than only unfiltered nearest-neighbor queries?Advanced
