These were the questions that were asked to me in the first round:

1. What are fixtures in Python?
2. What are setup and teardown methods?
3. What are iterators in Python?
4. What are namespaces in Python?
5. How do you write synchronous code inside asynchronous code in Python?
6. What are blocking I/O and non-blocking I/O?
7. What are parameterized decorators in Python?
8. What are stored procedures in SQL?
9. What is a context manager in Python?
10. What are the disadvantages of using a monolithic architecture?
11. How do you migrate from monolithic to microservice based architecture?
12. How would you improve the querying if say a database had millions of rows?
13. What are the disadvantages of an index?
14. What is an event loop (in Python?)?

And then a coding question :

• Find the longest substring without a repeating character.

The interview was supposed to last 1.5 hours, but mine ended in 45 minutes. I think I may have been rejected.
