Ho presentato la mia candidatura tramite segnalazione di un dipendente. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso Zafran Security (Tel Aviv) nel mese di lug 2025
Colloquio
First interview with the Team Lead, great talk, deep dive into system design and questions about personal projects.
Second one with the Head of Engineering, similar to the first interview but with different questions :)
Besides that, short interview with the CTO.
All in all, great process, great people!

Domanda 1
The frontend has an “Export all” button for a large table of cyber threats.
Clicking it starts an asynchronous export, shows a progress bar, and downloads the file when ready.
The backend is built from microservices communicating via gRPC.
The task was to:
Trace the export flow across services & explain how progress is tracked and reported to the UI
Design the complete export solution, including async execution, progress updates, file generation, and download
Discuss scalability and design tradeoffs
