Exactly. The job of the recruiter is to send - days in advance - invites to everybody involved, ensure they are not busy and they affirmatively accepted the invite. Even if somebody doesn't keep one's calendar up to date - if invite wasn't confirmed the recruiter should have known and should have done something about it. Looks like serious quality problems in that department in Google.
Now, let's say there was some royal but completely understandable cockup where this guy completely spaced that this day was the interview or whatever. Fine. Where was the recruiter in this? Who was in charge of the process, and why didn't they realize that an interviewer was unavailable sometime in advance?
If I get an interview with a company and then just neglect to show up, odds are they will not give me a second chance unless I had a good reason, something more than just "I forgot". Why should things be any different if the roles are reversed?
