I applied through a staffing agency. The process took 5 days. I interviewed at Dimensional Fund Advisors (Austin, TX) in Nov 2013
Interview
Phone screen interview is very simple, not a lot of technical questions.
First interview is meeting with Manager,Technical interview by team mates, the questions were all .net related.
There is a coding test at the end. Its very simple, if you have few months of experience with writing code, you will do well in the coding test.
