Application

I applied through college or university. The process took 2 weeks. I interviewed at Yammer in February 2012.

Interview

On campus interview followed by a phone interview, both with a member of data analytic group.
Both involved questions about your experience, some probability questions, elementary coding questions and relatively easy stat modeling questions.
First interviewer was more willing to walk me through the problem if I reached an answer in slightly different way. Questions were like:
- Derive an expected value/ probability of an event given a situation.
(Some questions are bizarre, but you are expected to ask clarifying questions so it is okay)
- Given a data matrix, describe how you'd count a number of occurrence of certain object.
- you are trying to evaluate the effect of a new feature on yammer, how would you quantify it?
Second was definitely more technical. Only couple of personal questions were asked: 1) he asked me to describe a "cool" project that I have worked on and 2) toward the end of the interview, he randomly asked me what my hobby was for which I was not ready.
- a+b=999 find a,b such that those two numbers are both prime numbers. (The answer is 2 and 997: after I answered, he asked me how would I verify that 997 is a prime number.)
- expected number of trials until you get the first head
- expected number of trials if you continue the experiment until you get two consecutive heads.
- on okcupid type dating website, assume you know the number of messages each user send out and whether or not the user gets a match (0-1); how would you measure the relationship between the two?

I didn't do too well on the second phone interview but I felt that the questions were reasonable at least.

Interview Questions

• what is your hobby in the middle of the technical questions was what taken me aback most. I guess you have to be prepared to answer any question with calm and chill under pressure.   Answer Question
