Applied online. Received an email about two weeks later for a telephone interview, followed by a face-to-face interview at the London office (two weeks after the telephone interview). The questions were fairly easy, focusing solely on C++. The interviewers were very friendly throughout the process. The office is beautiful, and I was especially impressed by the cafeteria!

• Difference between call by pointer and reference
• Polymorphism
• Vptr, virtual table: where is it stored?
• Size of an empty class: why? With a function? With a virtual function?
• Constructors
• Copy constructor
• Static members and static functions

In-house:

• Program to reverse an integer array.
• Program to generate a random number in the range 1 to 200 with equal probability, given a function that always returns 1 or 0.
• Inheritance
• Question on logical operators
