This hasn't really matched my experience with the industry. Honestly, most of the hires I've made that have done exceptionally well are the folks who have a very solid grasp of the fundamentals. I prefer them over a subject matter expert in a framework all week long. If you can't pick up a framework as part of the job, you're a really mediocre developer. Does it require slightly more on-boarding time? Sure, but that's a pretty cheap price to pay for a solid long-term employee. I've had the same experience on the other side of the table as an interviewee. I'll flat out tell them I've never touched their framework of choice. Or used their language of choice. It really doesn't matter as long as you can talk competently about the concepts behind them, and have a good track record.
