Do you support written interview questions for the senior experience candidates, which is followed by most companies in Middle East?

I think the writing interview is the best way to explain a complex process that requires drawing (such as Value Stream Mapping of an example process that you wanted to show them!) or an example of a Root-Cause-Analysis etc. Like one of the above participants said, if they are good at speaking vs. writing, it may be not in favor of them.  So, it depends on the individuals capabilities of being a good speaker or a good writer.  If you as a candidate possess both, good for you.

Written  question will not be the only way to help the wright selection of candidates , the most professional way is face to face and all questions and answered should be written and documented during the interview process   , we are human we still need to use our common sence as well . thanks

In my opinion the best thing is to not depend on a sole method, some people are good researchers with many information and can speak brilliantly but cannot do much on ground, while some are not very good at marketing for themselves however they are really good practically and have vast knowledge. so you might need to interview them face to face, have them answer some quastion in writing, get reference checks from previous employers, or even assessment centers.
