Filter employees whose name contains 'a' (case-insensitive) .Where(e => e.Name.IndexOf('a',?

Short answer: var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var…

Explain a bit more

filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0);

Example code

var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0); var filtered = employees StringComparison.OrdinalIgnoreCase) >= 0);

Real-world example (ShopNest)

ShopNest filters active products with products.Where(p => p.IsActive && p.Stock > 0) before showing the catalog.

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.
