Indian School of Business (ISB), Hyderabad Placement Interview Questions

Candy crush is seeing a steep drop in the number of users between level 6 and 7.What can be the causes?
The difficulty level (too high in level 7) or fatigue (people are getting bored/tired by the time they reach level 7)

What test would you perform to find the cause?
Make the difficulty of level 7 same as level 6. If we see the same pattern, it would be due to fatigue

What's another way to do the test?
Replace level 5 with level 7. If the problem is difficulty, we would now see a drop between level 5 and 6.

Amazon saw a very steep decrease in revenue today.What would be the first question you would ask? Answer to that question should lead to 2 different approaches.
Was there a drop in number of users visiting the site? If yes, we need to check why users did not visit amazon for their purchases. If no, we need to check why they purchased less as compared to regular amount.

There was no drop in the DAU. Nothing external. No change in functionality of the site. Now how will you proceed?
Trace the user journey:

1) Lands on the home page (we know the user has visited)

2) Types in the search box or clicks on one of the categories or offers

3) Lands on results page (list of products, filters, etc.)

4) Clicks on filters to narrow down the results or clicks on an item

5) Lands on the product details page and selects buy now or goes back

6) Cart and Payment pages

There was a drop in users reaching the product details page. What would be your thought process (general idea not specific to a product category)?
Means users are reaching the results page but not going forward. Factors: Relevance and Product Descriptions.

Evaluate each one of them to check if something has changed Relevance: Clicks on first page of results? Position of the clicked item in the list? Navigation to 2nd page? Usage of filters? - Change in these statistics can tell us if the results were relevant to what user was looking for.
Product Description: Name, Short desc, Reviews, Amazon fulfilled, prices - Check if any of these factors have changed for the category that would be facing the problem.

A game where you get to dress up avatars using different apparels, jewelry, etc. As creativity is subjective, how will you judge the work of players and build a points system?
I don’t fully remember my answer, but following were some of the points I made: • Let players judge each other's work • Provide incentives for players to judge as many avatars as possible • Show them two avatars and let them pick the best one. The picked one gets points. This provides a frame of reference for players to judge.

Per day revenue of Swiggy in Hyderabad. Puzzles: 2 ropes of different lengths and non-uniform cross sections/density. Each takes 1 hr to burn. Measure 45 mins. 1 ant on each vertex of a triangle. Each can go along any of the two sides connected to the corner. Find the probability that none of the ants collide.
: (Dos and Don’ts, What went wrong.. , What went right.. etc.) Interviewer was pretty chill and very helpful. Whenever I was going in the wrong direction, he was asking me questions that can help me get back on track. Also, as they provided multiple cases, don’t worry if you screw up one case. So be calm and take your time to answer the question. They were looking to understand how you think, and not for a structure from any book.

Puzzle - I have a Mathematical logic in my mind, and I would give you three numbers that satisfy that logic. You cannot ask me questions but can only give me three more numbers to which I would reply ‘yes’ if the numbers satisfy the logic and ‘no’ if they do not. You can ask unlimited number triplets, but you have only one shot in solving the logic. The numbers are 2,4,6. (E.g., If I say 3,6,9, the interviewer will respond as ‘yes’)
The numbers are in ascending order ( The key here is to eliminate all possibilities and not jump to conclusion)

Graph based- level based games-users playing suddenly drop at level 6
For this round, try to show the breadth of thinking by coming up with multiple features and solutions. Also discuss the priority. Having some knowledge of mobile games could help understand some questions better but it is not a MUST. You canask for explanation or clarifications on what the flow of the game is and the interviewer would provide the same.
