Any tips for job interview (.NET/c#)?

Don't lie.

Be polite and nice all time, don't get upset by attitude and of interviewer questions. Take time to think about it and be natural.

I have a ton but here are the main ones. They may ask which part of they stack you feel most comfortable in. (Back end, middle, UI) Don't be surprised by a white board question like fizz buzz. Be prepared to be ask questions about database experience including sql and database design questions. Study the top .net interview questions, you will likely be asked some of these word for word. Understand solid principles. Be able to talk about testing, usually not in depth but your experience and philosophy. Be prepared to talk about how you access data, for example entity framework, dapper.. How do you organize yourself. What do you do to improve or widen skills. Which JavaScript frameworks you have worked with recently. I have been on both sides of the table many times.

Show your excitement for the job. Research the company. Know what big projects they are working on. Never ever bad mouth your current or past employers. Good luck and get that job!

Here's some interview questions I've been asked in c#,
Inheritance, sealed classes, ihttpactionresult vs HttpResponseMessage, why would you mock a DB. What is TDD. What is postman?

thank you guys
