I applied online. I interviewed at Chitika (Westborough, MA) in May 2013
Interview
Initial chat with the recruiter. Phone screen (first one was cancelled without notifying and then rescheduled one started more than 15 mins late). On site interview with a couple of people. Standard logical problems and some database and php questions. Then they gave me a programming exercise to complete within 3 days.
Interview questions [1]
Question 1
Nothing too difficult if you know how to solve logical puzzles.
