What do you know about Amex?
First case - you have data about the users of IRCTC app - login time, usage time, clicks, services, demographics etc.
IRCTC wants to launch air tickets booking service on the app and for this they will first show a pop up advertisement to inform their existing users about this service. Tell the parameters or criteria's to clean the data to come up with the target group to whom they will show this ad and are guaranteed to use this new service.
You have mentioned photography as your hobby. I know there is already a photography club in the campus but suppose you want to come up with a new but niche club only for select users who have high experience.
Suppose you have a genie, who can get you any database from any source which could be of help to you. With those data points overlapping over one another, you will eventually come up with a new data of users who are most likely to join your club. Tell me from what sort and type of data you will ask him to fetch and why? What information are you exactly searching for through those?

Interview Preparation Tips
First define the problem statement and write down all requirements on paper.
Writing down the requirements and clarify the assumptions are two most important task in any system design question.
Remember nobody expects you to design fully functional auto-correct functionality, or Zomato app, or parking lot in one hour.
It took many months for any development team to get these kind of design right and sometime applications have to be redesign multiple times in reality.
In interview what people want to see is that how well you think,are you able to connect the dots in your design and can you come up with high level prototype which is generic and scalable.
I have seen people got lost in little nuances/edge scenarios which doesn't matter in larger scheme of things, so
1. Focus on big picture first.
2. Get your high level entity design, Schema Design right.
3. Then connect the dots and focus of if we can scale the system or enhance the system if required.
4. Try to accommodate any edge case scenario.
Generally, if you get first three steps rights , in one hour or so that's enough for you to crack the round.
