I've only walked right into a job once. I had worked with one of the head guys at another job, weeks before they hired me. So they clearly knew I knew my stuff and was capable. I've found it's very rare to do this nowadays. Even if you know someone at the company, you'll likely get grilled in a technical interview. Unless it's a very tiny company / startup.
