Summary

Round 1: Technical Phone

Question: The interview started 10 minutes late. I was asked about inheritance vs polymorphism, including writing an example of inheritance overriding a parent class method. Then I was asked about constructors vs destructors, with a follow-up about whether Python has destructors. I also answered a couple of standard questions that I don't fully remember.

Details

The coding question I received was to print every odd number in a given integer list, with the following follow-up questions:

1. What if the list contains negative numbers?
2. What if some integers are so large that they do not fit in 32 bits?

My approach:

1. I iterated through the list and checked if each number was odd.
2. I printed the odd numbers.

Key insights:

• Consider edge cases like negative numbers and large integers.
• Be prepared to discuss the time and space complexity of your solution.
