Recruiter contacted me via LinkedIn, followed by phone screen with the Hiring Manager. Within couple of weeks received a call to appear for an on-site interview. The time between being contacted for the first time and receiving a final decision regarding an offer/rejection was about one month.

It was a good interview with medium-to-difficult questions. It took 4 rounds of technical interview. You should have strong fundamentals and analytical thinking to crack interview. You need to demonstrate your experience and skills smartly and apply your skills wisely.
