will cfa be any relevant as in job, career and learning prospects 5 years from now ?

Based upon your question, assume that you are not working in a related field or in a full time profile which requires CFA

You want to use the credentials to break into the field or accelerate your career.

My 2 cents in your unique position.

If you are young. As in will be able to complete L3 before 25, then go for it. Else it's a waste. You won't be able to reap max benefits out of it.
