Other side of the table

I never interviewed anybody for a technical position and currently as one of my team member left our team, I was assigned to hire a asp.net developer position for our team. It is quite a experience as you need to filter the resume based on our requirement. I interviewed three guys so far and still did not find a good fit. Sometimes, I used to think whether I am so picky. But my questions are simple and all I need is a direct answer. This process made me think like how I would act if I am in other side of the table! Today I got to interview one person who played lots of managerial role in various project and only know the basic concepts of asp.net but this position requires serious asp.net skill and so I was not comfortable in asking some of the asp.net specific questions to him (when I know that he is not going to answer)

My typical questions list was like this.

1. Life cycle of page

2. Difference between Datareaders and Datasets

3. Best feature you like in you asp.net or like to have

4. Explanation of postback

5. Authoring tool they used/Accessibility issue they faced in their last project

6. State management

7. Difference between Application object and Cache object

8. Page level error handling

9. Difference between Web User Controls and Web Custom Controls

and some SQL questions and architectural questions

We are going to keep trying until I find a right guy but our time is limited too!!
