I was initially contacted by HR to go over some basic points on my resume and to set up a technical interview.

The person I spoke with on the phone seemed a little resentful that everything was provided by Google for Google employees, as it was very difficult to not spend a lot of time at work.

If coding is your passion, then it sounds like Google takes care of the rest.

The lady from HR seemed rather more upbeat and enjoyed the people she worked with.

Easier questions

1. Two variations of a program exist, A and B. When run on machine 1, A runs twice as fast as B. When run on machine 2, A runs 10x as fast as B. How would you investigate this?

• Same datasets
• Same versions of OS and libraries
• Same hardware

1. Had to code a method that calculated the factorial, first simply, then a second one recursively.

Trickier question: Code a method given the following method signature that will print out any numbers that intersect both arrays of numbers.

// Example arrays // 4, 18, 25, 40, 411 // 20, 25, 40, 320, 1009, 1100

void intersect(int[] arr1, int len1, int[] arr2, int len2) {
