I think managers who don't know how to interview strong technical candidates will find it hard to hire people with different skills to what they think they need.And therefore find it hard to see how useful someone who has 5 years Node experience can be in a role where they need someone with two years React for example (I've worked with great Senior developers who transitioned very smoothly from Java Servlets to React). But then again I suppose from a HR perspective,the line has to be drawn somewhere.
