Dear Naveed, As you can see above that Ms. Shabnam has very well clarified regarding what we need to prepare for during the interviews. Moreover, I will add up to this that no one has to take interviews for granted, as an extraordinary circumstance may badly effect us; thus we need to dress up well and show up to them that we are right choice and we don't have any extraordinary issues.
In short we have to show that we are as normal as any human is
Regards and Best Wishes to All
