Thanks. I've turned down a couple interviews knowing I'd bomb at least one, didn't want that on my perm Google Record. It's nice to know it's not just me, and also there's redemption.
This is a bad strategy. One thing that actually helps you tremendously is evidence of growth. The easiest way for the hiring committee to see this is for you to show improvement from a previous interview.
I guess it'd be possible to game this signal, but that's a lot of effort and still just one signal.
My real point is that it absolutely does not count against you.
Fair enough, and I agree to an extent. But when I got that packet of prep material, I froze. I may go down that road again in the near future, but I want to be mindful of thresholds.
