I applied through a recruiter. The process took 3 days. I interviewed at GraphScience (Palo Alto, CA) in Apr 2013
Interview
Initially I was contacted by a recruiter and set up an initial phone screening. I had the phone screening the next day. The interviewer asked me about my background and past experience, specially related PHP and MySQL. Then she decided to move me to a coding test phase. I was given the test by email later that afternoon, and asked to complete the coding test within 2-3 days. I completed it in two days and compressed and emailed my code in .tgz format as requested. The interviewer replied and acknowledged she had received my code and would get back to me the next week. However, I did not receive any word from them.
