I am new in the field of analytics. I have done a base sas course and i am trying to find job on the basis of that.
Recently i faced ine interview in which interviewer asked me following question:
Interviewer : He said he just want to test my business intelligence . He gave me a case and said suppose there is a pizza shop and pizza shop has come with a offer that if he is delayed by 30 minutes in home deliveries he will deliver it for free…so as an analyst what would you suggest them either to accept or reject that offer.
Me : I said that i would look into the historical data and would figure out the delay time in the near by areas and would see the frequency of the customer after being delayed and the effect on the sales and then will decide that.
Interviewer: But you dont have any historical data and you have to take descision now.
ME: I will try this offer for a particular period of time and then will see its effect in sales if there is decrease then i would reject this offer.
Interviewer : But you find out that decrease is from some other reasons then?
I just want to know how to tackle these types of questions please help me and guide me how to prepare for the interview.
Pizza chains having this rule of 30 mins delivery time can be based on many things like:
1.Location of the pizza delivery store.(It should be located kind of centrally in the area it wants to service.)
2.The number of delivery boys it has.
3.The traffic conditions and many more.
However they give this offer to entice customers into thinking that if it is late they will get it for free.
Also sometimes there might be late deliveries but if they are only a small proportion of the total deliveries it is not a problem.
So you see it will depend on many factors as mentioned above and if the pizza chain has the required infrastructure to deliver within 30 mins within the specified distance limits(say only 5km of area around it) it can surely go for this offer.
Also there is never a right or wrong answer to such questions and interviewers basically check your logical reasoning skills through such questions.

Hope this helps!!
