A Strange Interview ......

The interview I had today is the strangest one I've ever encountered .........

Pls have a seat. Do you have a photo with you?
Can you pls introduce yourself ?
Our post would mainly responsible for .......(introducing the duties and their programs)
Do you feel confident in teaching?
Do you have any question to ask?

That's it ...... The interview only took 5 mins ....... and half of that was the explaination of the duties of the post ....... Isn't it too short ?????

Isn't that the purpose of an interview is to find out a suitable candidate for the post? With these questions the interviewer could really be able to grasp a better knowledge of each interviewee and pick up the suitable one?

Or is my problem for not presenting myself as fully as I could in the interview??????
Or they will ask more and get more information in the second interview ??

If I'm able to get into the second inerview, I may be able to know the truth behind.
