If you are planning on interviewing at other companies then the answer is an astonishing YES.

I have discovered this myself in recent interviews. If you are a front end developer expect to know React and expect to be interviewed by a supposedly senior developer who hasn’t touched anything in the front end outside of React.

This is so prevalent (and I have no interest in React or other frameworks) that now I immediately attempt to disqualify myself from any position brought to me by mentioning I will not interview with React. This has saved me a lot of time and disappointment.

Strangely I have also observed tremendous interest in TypeScript at just about everywhere, but TypeScript experience is irrelevant if the company is not already actively writing code in it. If a company mentions anything TypeScript keep this mind so that they aren’t wasting your time.
