Your job is to recommend 2 food items to a customer new to the restaurant. Answer the following questions:-
a. Looking at the data, provide 3 findings for the restaurant to boost their performance
Proposed Solution.

ii. A list of the most popular food item
iii. Looking at the customer’s age and sex you can decide what to offer to a new customer. If the data suggests that a girl in the age group 20-25 likes chocolate ice cream then you can recommend this ice cream to the new girl customer 

b. Think of 4 more data points which might help you with the analysis

Proposed Solution
i. Pincode of delivery

iv. Date and Day of service 

c. Now, what else can you find out from this data?

Round 3 – Case Study
Topic – Profit of a company selling mobile back cover is declining. List out all the possible reasons



Following is the way in which discussion proceeded with the interviewer:-
1. The demand itself has declined i.e. customers are not using cover that much. Asked to think more by the interviewer
2. Maybe the competitor is also facing loss which again means that the demand is low. Competitors are making a decent profit
3. Bad Marketing – The company is not putting stalls or shops in a crowded place. The interviewer told that the company was making a decent profit 6 months back
4. Maybe the footfall of the mall or place decreased. Could be(first positive response)
5. Maybe a popular mobile phone shop has shifted somewhere else. Could be(again a so-so response)
6. Maybe the other companies have reduced the price of their product which is why customers are drifting to these companies. The interviewer seemed pleased
7. New technology in the cover market to make covers more durable and the company we are talking about is using the same old technology. Seemed good enough point
8. Since we are talking about back covers, there could be new or trending designs which are not produced by the company
9. The company has not registered on different e-commerce websites and the website they are present on is not doing good business. He looked satisfied with the point

There were discussions on each point. The key here is to understand the point if you think it is not making much sense in a discussion. If you think you are unable to convey the point, you should try to justify the point.

If it’s correct, hang on to the point.
If you think it was a miss, admit it and move to the next point.

Keep practicing and keep looking for new problem statements.
