Dear Suganyahari,
As such there is no qualification is fixed for "who can" or "who can not" take interview. But you need to follow the procedure to take an interview.
For e.g. a person A starts his own business, he might not be having knowledge about Finance OR any other section of the business. But he will be the person who will be interviewing the person for his company whether he has the knowledge or not..
Now the golden rule is that you should be clear that as to what you require from that position.
If you are working in a company, and require to take interviews. my suggestion would be
1. Develop an Job Description for that profile - what exactly you are looking in that profile
2. Develop questions - you yourself need to develop questions regarding that position by looking at the JD. which will be asked in the interview.(otherwise take help from internet)
for e.g. if you have to take a interview for accounts manager position then you need to work on the JD of that profile and further looks for question that are relevant for that position.
find enclosed an word file to help you on taking interviews. feel free to contact for more information.
Thanks and Regards,
Deepak Sabharwal
