After college I did 3.5 years of Java with spring, used orm and wrote SQL, also did nodejs. But then I did like 7 years of purely front end. obviously I'm rusty with the syntax, but all the oop, DI concept, design patterns and how stuff works , those concepts you never forget. I have seen boot campers calling themselves full stack because MERN stack (see my not before jumping) and also applying full stack roles. Will it be wise for me to apply for fullstack roles too? Note: not trying to minimize bootcamper, I know very talented boot campers. It's more about me, not sure if it's imposter syndrome because I feel I'm not qualified and boot campers have fresher what they learn.
