- I was asked to design a Food Delivery App (Swiggy). This round revolved around designing database schemas. I was given around 20 minutes to identify the various entities involved in the system, establish the relationships between these entities and also identify the primary key – foreign key constraints.
- After 20 minutes, we had a good discussion on my findings and corrections with respect to certain attributes I may have missed out on in my design.
- A few complex SQL queries were also asked related to the above schemas.
