Stay away from companies and recruiters who ask you to be familiar with a laundry list of technologies, IMHO it's a red flag. If you kill it on the CS fundamentals and programming practices/patterns, then it shouldn't matter whether or not you are an expert in dime-a-dozen technologies like state management frameworks and view frameworks. Anyone worth their salt as a developer can learn and be somewhat productive with a framework in less than a week on the job.

I'd rather pay a math/engineering graduate who knows nothing about React than a bootcamp student who has had a year of experience with React.
