Intern Interview

Intern
Austin, TX

I applied online and the process took a day - interviewed at Google in March 2013.

Interview Details – I applied for the internship position very late (in Mar), but still got the chance to give the telephonic interviews. The first interview involved a detailed discussion of only one coding problem (that I couldn't solve completely), and I was asked two simple coding questions in the second one.

Interview Question – 1st interview question -
How can you merge k sorted data streams using O(1) RAM? Also, explain in detail how will you define the data stream object and its related functions/operations.

2nd interview questions -
1. Write a code that accepts integers as arrays and outputs the multiplication result as an array.
2. Write a code that takes the coordinates of multiple rectangles as input and returns as output the coordinates of the rectangle that is the intersection of all the rectangles.

I applied through an employee referral - interviewed at Google in April 2011.

Interview Details – Was referred by an employee and obtained two 15 minute phone interviews. The interview questions were standard however the interviewer professionalism was extremely low. The first interviewer did not call at the scheduled time... period. The interview was rescheduled and the second interviewer also did not call, after waiting 30 minutes I called them and was told "he had gotten busy with something". The interview was then conducted.

Interview Question – Typical low level CS questions about sorting algorithms and operational cost.   Answer Question

I applied through college or university and the process took a day - interviewed at Google.

Interview Details – Got asked for an on-campus interview with 2 interviewers, 45 minutes each. Both asked me questions on binary trees, while splitting their questions to part, a, b, etc., with each additional part asking the likes of "well, now assuming ______ no longer work/can't be used, how would you do it?". Interviewers were nice.

Interview Question – The concepts aren't hard, but requires thinking and has twists on the questions that you might have seen from interview books and such.   Answer Question

Interview Details – Submitted my resume online, talked to representatives, and got a phone interview about 2 weeks after. It was two 30 minute interviews.

Interview Question – Nothing unexpected, they ask you to write short algorithms that would solve their questions. Mostly string related stuff because my interviewer was working with Google Books. And one theoretical question at the end.   Answer Question
