Which is to say that since the Indian education system as described in the article doesn't teach problem solving, and since you want people who have some problem solving ability, you must ask them to solve a problem in the interview.

But, I find the article confusing, it is about how a call centre company is struggling to find people who can't think outside the box... why the heck does a call centre company want people who can think? Aren't they just going to follow the same script day in and day out?? Wouldn't the ability to think for yourself actually be a curse at a company like that???
