/shrug. When I was considering positions in SF a few years back, I was chatting with hiring managers I'd be under first before going through any whiteboard interviews. Maybe things have changed?
Honestly, this I'm perfectly fine with -- if you need a calibrated panel to assess your eng bar. What is annoying (the case for Google MTV for me at least) is if gatekeepers block you from identifying if there is potential fit in the first place.
