      I applied through a recruiter. The process took 1 day. I interviewed at Comcast (Philadelphia, PA) in Mar 2017

      Interview

      Recruiter messaged me in Linked. Had a call with recruiter and asked about my current projects, salary, achievements, goals..etc. Recruiter forwarded my profile to hiring manager. Had a 30 min telephonic conversation with hiring manager. It was a high level discussion. Then they invited me for onsite interview at Philadelphia, PA.
