Short answer: var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var…

Explain a bit more

combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}");

Example code

var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}"); var combined = employees.Select(e => $"{e.Name} - {e.Department}");

Real-world example (ShopNest)

ShopNest uses LINQ to query orders: filter by date, project to a summary DTO, and order by total—readable C# that becomes SQL under EF Core.

Say this in the interview

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.
