I applied online. The process took 4 weeks. I interviewed at X in Jul 2013
Interview
The process was typical starting with a call from a recruiter followed by two technical phone interviews. The first technical phone interview was statistical where the interviewer asked about A/B testing and how to measure engagement. The second was engineering based where I had to code using collabedit.com. Then the culture test is done on site for a full day.
Interview questions [1]
Question 1
Given twitter user data, how would you measure engagement?
The recruiter got in touch to set up a screening call. I was asked basic questions concerning my background and my motivation. Then we had a coding challenge with a question I later found on LeetCode under the Twitter section for the last 6 months.
Case study was interesting; interviewer was previously from uber so some similar interview questions, techniques do apply, overall a good engaging exercise. Nothing to complain about. Overall it is okay
