Got the email from the manager to schedule the phone interview for one hour. All the questions asked were in C++. The interviewer was friendly, and the interview took for exactly one hour.

1. What is the difference between virtual and pure virtual functions? Explain them.

2. What are a constructor and a destructor?

3. Can we override a constructor?

4. Provide pseudo-code or an algorithm to distinguish between even and odd numbers within a range of numbers.

5. One question on the angle between the minute and second hands, something like how much distance traveled (never expected).

6. What is a tuple in Python?

7. What is the difference between C++ and Python?

Some other easy questions... (Don't remember exactly). I answered most of them but received a reject after 2 days.
