The process took 1 day. I interviewed at G-Research (London, England) in Feb 2012
Interview
They immediately replied to my application and offered the opportunity to visit their premises for a skills test.
This was an one off test, which means that failing to get their standards does not give a second opportunity.
Very friendly environment, great and intelligent people, though were looking for something else, with more ability to write very efficient code. The company's culture though seems really interesting.
Interview questions [1]
Question 1
Due to information disclosure signed, I am unable to give more information about the test taken.
The interview process was thorough and well structured. It focused primarily on data structures and algorithms, and the level was broadly in line with what you would expect for a software engineering interview of this type. I cannot share specific details of the questions, but standard preparation in algorithms, data structures, problem solving, and coding under interview conditions should be sufficient. Overall, it felt rigorous but fair.
There were mostly algorithmic questions to be solved on a whiteboard. Then, after a lunch with a couple of the junior staff, the tell you whether you’re into the next round. There is also a test beforehand.
2-3 parts depending on team. Pretty in depth on topics. 2 coding rounds I believe. Interview process is fairly quick. It’s not a process that takes 3-4 weeks. 2 weeks max, 1 week if you’re really adamant.
