Are all employees earning more than 50k?

Short answer: bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary >…

Example code

bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000); bool allHigh = employees.All(e => e.Salary > 50000);

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.
