Ask HN: Why does Google get away with such bad recruiting practices?

Recently I've been through the on-site interviews at Google and had a terrible experience. The recruiter went silent after my on-site and my calls are directly going to voicemail. The on-site was a month ago and I've heard nothing regarding my status. I've shared this experience with some of my friends, and they've all had similar experiences. My question is - how is Google getting away with such bad recruiting practices? I've never had a company not call me back after I took a day off work to interview, even if it is bad news! Shouldn't bad recruiting practice like this hurt the company's reputation? And shouldn't people be more hesitant to apply to companies knowing that they will be treated badly?
