Société Générale Software Engineer Interview Experience: concurrency and the Saga pattern

The interview focused on technical questions about concurrency and reliability. The interviewer asked about multithreading, including deadlock and livelock, then pushed me to reason through how I would resolve several multithreading exercises.

The conversation also covered microservices, particularly the Saga pattern and fault tolerance. It was more about working through system behavior than remembering small details, and the difficulty felt average.

I did not receive an offer, but the process itself was coherent. Each question seemed connected to designing and debugging distributed behavior under stress.

Location: Paris. Overall feedback: positive. Offer status: no offer.
