> decrease in the perceived prestige of an engineering job at Facebook
Actually FB became a haven for xooglers that wanted to escape deteriorating engineering at lower levels at Google; there is still burning spirit of hacking present, even after IPO. FB works hard to retain it (outside noisy open offices though).
If you ever went through engineering interview process at FB, you'd have noticed it's one notch better prepared than the one at Google. Their Glassdoor rating is even slightly better and there are very few companies that are rated better (and usually smaller like Odersky's Lightbend, JetBrains...), so there is almost nowhere to go for a better engineering experience.
