I received a referral from a friend, applied online, and was set up for a phone screen.

The HR representative was misleading; she did not forward all my materials to the interviewer and explicitly stated there would not be data structure or algorithm questions, though the interviewer did ask technical questions.

The overall interview lasted about 20 minutes.

• Describe in detail your most involved and difficult project that you've done in the past.

• What is the difference between objects and classes in C++?

• You're given two arrays of strings. Determine if all the strings in the first array are present in the second array and return a boolean. Now assume both arrays have a million elements each. How would your answer change to improve efficiency?
