The process took 3 weeks. I interviewed at Model N (Redwood City, CA) in Oct 2011
Interview
First had detail telephonic interview. After being selected was asked to come down to office, where I was interviewed by 3 ppl. HR seems to be quite slow in response or might have more applicants but I had to follow up to know what is the result.
First they told me to hold on and then they said, they have some other candidates.
