Google

Contact via email from a recruiter inviting to the process. The interview with HR took place, followed by a Google questionnaire and, subsequently, a live coding technical interview.

Very good. You have to be good, be focused, pay attention to the answers. They will choose the guy who stood out, if you like what you do.

Phone interview and on-site with 4 Googlers. Some of them went really well, and others not so much. Ended up not getting an offer, but the overall experience was nice. The recruiter took too long to reply about interview results.
