IMC accepted my CV and promptly scheduled a phone interview. The interview was short and concise, mostly used to detail the application process.

From there, I took a numerical, verbal, and diagrammatic test, which sent me through to the next round for a programming assessment. This involved completing three different tasks, none of them overly difficult.

They invited me to have a Skype interview, which entailed almost entirely reviewing the programming tasks and asking me about my implementation and corner cases.

How would you create an abstract method which could return either an int or a double?
