In short
Backend work is team work: API contracts with frontend, schema changes with other services, on-call with your squad. Interviewers listen for how you communicate, not just what you built.
Behavioral questions about working with data scientists, product managers and engineers — AI projects are rarely solo, so this gets tested directly.
Think of it like this
Maggi night in the hostel
One friend boils water, one chops onions, one finds clean bowls. It works because everyone says what they're doing and nobody adds salt twice. Good teams split work clearly and keep each other posted.

A STAR answer about working with frontend
1/5"In our hackathon team, the frontend kept breaking because my API responses changed shape."
The big ideas
What you need to know
Use STAR
Situation, Task, Action, Result. Keep setup short and spend most of the time on your actions.
Contracts reduce friction
API specs, shared types and clear tickets mean fewer "it worked on my side" arguments.
Flag problems early
"This will take two extra days" on Monday is helpful. On Friday evening it's a crisis.
Credit others
Mention what teammates did well. It shows you notice and value other people's work.
Save yourself the pain
Common mistakes
Oops
Telling a story where you were right and everyone else was wrong.
Do this instead
Show how you understood the other side and reached an outcome together.
Oops
Only using "we", so your part is invisible.
Do this instead
"We shipped it; I designed the API and set up the mock server" makes your role clear.
