I applied online. The process took 2 weeks. I interviewed at G-Research (London, England) in Nov 2013
Interview
I applied for Software Developer Internship at G-Research on their website in early November. Two days later, I was invited to participate in some interviews at their assessment center. When I got there, the first step was to take a test from 11 to 12 consisting of around 20 CS general knowledge questions. After that I had lunch and afterwards I was told I have passed the test and I'm going to have 4 more interviews. At the end of the week I received a rejection letter.

Question 1
Unfortunately, I have signed an NDA and I can't go into question specific details. Be prepared to answer questions related to various CS topics.
Consisted of a series of problem solving questions and programming exercises. The interviewer was friendly and the problem solving felt collaborative. Also included a high level architecture question about how one would design a route planning app.
