I took an online challenge on HackerRank Jobs. It consisted of 6 code reading questions and 2 coding questions, all to be completed within 1 hour.

The HR representative called me one day later and sent me a code fragment that would be discussed in the technical interview. The code fragment was about virtual functions and multiple inheritance.

The technical interview lasted for 1 hour and we discussed the code fragment in detail. They asked about:

• The implementation of virtual functions
• The memory layout of a multiple inheritance object
• Numerous questions on this pointer adjustment.

Implementation details of vtable and this pointer adjustment in multiple inheritances.
