There's an interesting thing out there people tend to notice during hiring sprees, and shifts and pivots in the IT industry.  That particular interesting thing is that whatever Silicon Valley tends to adopt, others tend to follow suit.  Not necessarily because it's "cool" or "popular" but because they know how to get people hired.  On not one, but five separate occasions with various interested employers I began noticing a pattern on these small startups that had that mentality.
