The interviewer was very senior and was asking very complex, scenario-based questions. The interview lasted for 1.15 hours. The requirement was for a UI Angular developer with unit testing skillsets.

Questions asked were typically for a person with 5-7 years of experience, but I only had 2 years.

Questions:

1. Angular component lifecycle: parent and child.
2. Timeout-related questions.
3. let, var, and const examples with complex scenarios.
4. Observables and Promises.
5. Adding elements to an array.
6. Unit testing questions.

And many more.
