I applied through an employee referral. The process took 1 week. I interviewed at Okta (South San Francisco, CA) in Jan 2013
Interview
I was recommended by a friend. The recruiter contacted me and gave an easy phone interview. Questions were just array manipulation and some overlapping date problems. People were very technical. They kept drilling down to get details.
I really liked the depth of this interview. Probably one of the toughest I have experienced. They were definitely looking for top developers.
Interview questions [1]
Question 1
Lots of questions about different architecture. One which came to mind is to design a job scheduler.
