Sample .NET Developer interview questions

Your interview is generated from your own profile — these show the style and depth to expect.

1. 1Your ASP.NET Core API slows down under load and CPU is low. What do you suspect and how do you prove it?
2. 2When would you choose a scoped vs singleton service, and what bugs come from getting it wrong?
3. 3How would you migrate a monolith to services on Azure without a big-bang release?
