for those whom downvote. Im sad for them. As interviewer,what point i ask specific formula while the basic cannot deliver?Each client have their own way doing thing.If the person can do hello world very quick ,for sure he can do any other thing with proper guidance.Some candidate quite scare first time and unable to solve big formula question. Stick with simple and stress level will reduce and i prefer too see what they do how they talk . Its just not about code formula but on how much easier interaction in the future.
