I applied online. The process took 3 days. I interviewed at Exponent (Washington, DC) in Jun 2010
Interview
I did an initial phone interview with an HR person (about 10 minutes). I then did a second phone interview with my potential bosses (about 25-30 minutes). I then came in and interviewed with 5-6 people and did a 45 minute presentation. The final interview with presentation was about 4 hours.
Interview questions [1]
Question 1
Most were general questions to see if the interviewer would like me and then they answered my questions. Relatively easy interview. The only issue was that this was over a few hours.
