If they were able to BS through the behavioral interview, then most likely, you didn't go deep enough. I haven't been burned by this process once. I have gotten to the end of an interview and decided a candidate was not being forth coming on details, and turned them down, but I've never ended up with someone getting through where it was a complete disaster. That's not to say that there haven't been people that weren't perfect and ended up letting go, or they decided to leave themselves. Behavioral interviews when done properly get very detailed. I often am able to discover exactly how much of the HTTP stack someone has worked on, for example, down to choices on parameters at the TCP layer, or asyncio libraries.
