In a job interview you can face with several topics. Even if you are applying for a C# developer position, you have a fair good chance that you will get a few general .NET, database- or webservice-related questions. Of course there are several checklists available online that try to cover these topics one by one, but Chandan Kumar Sinha, a software developer from India, thought that a blog could be a better format.
On the .NET Interview Cracker blog he publishes about 2-3 posts every week and touched C#, .NET, SQL and webservices so far. The posts are not in question-answer format, but instead he summarizes the most important aspects of the topics. This format is great also for professional developers, because it helps to refresh and set out long learned concepts.
