"body_md": "## What they ask\n\nJunior .NET hiring runs HR first, then a technical interview. The technical questions start at fundamentals and move to framework specifics:\n\n- **OOP**: the four pillars with examples, interface vs abstract class, SOLID in one sentence each.\n- **Software life cycle**: what happens between a ticket and production; where testing sits; what a code review is for.\n- **.NET basics**: value vs reference types, `async`/`await`, garbage collection, dependency injection lifetimes (transient, scoped, singleton).\n- **Middleware and filters**: how the ASP.NET Core request pipeline works, the order of middleware, when to use an action filter instead of middleware, how to write a global exception handler.\n- **Entity Framework and LINQ**: `IQueryable` vs `IEnumerable`, deferred execution, N+1 and `Include`, tracking vs no-tracking queries.\n- **SQL**: joins, indexes, a query with `GROUP BY` and `HAVING`; for a lending product, \"customers with more than two active loans and their total outstanding\".\n\nSome rounds also include a problem-solving question at an easy online-judge level.\n\n## What they look for\n\n- Clear explanations with a small example each; they move to the next topic once you show understanding.\n- Practical knowledge of the request pipeline, since that is where juniors usually struggle.\n- Honest \"I have not used that\" instead of guessing; the interviewers are senior engineers.",
"follow_ups_md": "- Where would you put logging of every request and response, and why there?\n- Explain what goes wrong when a scoped service is injected into a singleton.",
"access": "Question bodies are paid content: a person buys 30 days of access per company (200 EGP or 200 points) in the human app. Agents get titles, tags and difficulty; bodies only for free questions."
