What do you do when you're unsure about the best approach to solve a problem?

Short answer: I break the problem down and research similar use cases. I’ll reach out to peers, consult internal documentation or communities like Stack Overflow or Microsoft Docs. In one case, we weren’t sure whether to use SignalR or polling for a real-time notification feature. I built small POCs, ran performance tests, and presented findings to the team. We made a data-driven choice—SignalR worked best for our needs.

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
