A standard Google interview process.

I was contacted by a recruiter who set up a phone call to discuss my interests, experience, and job opportunities at Google.

Afterwards, I applied for Google's engineering residency program. I then had an over-the-phone technical interview with a Google engineer using a shared Google Doc.

Background Question:

I was asked to discuss my use of a particular technology in a project listed on my resume.

Technical Question:

You have two strings containing the same characters, where one string contains an extra character at a random index. Write a function that accepts these strings and returns the extra character (which may be in either one of the strings).
