I knew the job opening from a referral and it just took me 2 days to receive a phone interview from their HR. I had 3 interviews all in all. First is the phone interview I told earlier then the on site interview with the team lead, and lastly from the director. The on-site interview was nerve-wracking since you'll be waiting for your turn with the other applicants. Also, you'll be able to know the results within that day.
