I applied through a recruiter. The process took 3 months. I interviewed at Landmark Graphics (Houston, TX) in Nov 2013
Interview
1. A written test, include math and your domain process
2. Panel interview process.
3. Followed by coding on their laptop.
4. Face to face with the director.
5. Background check takes forever, then their outsourced agency didn't provide the correct information, so I had to provide my W2s.
