Good advice. The only way to stay competitive on the programming market is to keep your skills up. Most employers hand out coding tests like candy, and online coding test platforms make things even easier. They might even give you a test before the interview, as this site suggests: https://www.testdome.com/

I would say that it’s not only useful to always be coding, but to build a portfolio of all your projects so you have something to show to potential employers.
