Bringing in someone inexperienced not only costs the amount of salary you’re paying for someone who doesn’t bring in business value, it also takes time away from experienced developers - costing even more.

Even worse, some junior developers do “negative work”. Work that is so bad, you have to take more time to undo the damage than just doing it yourself.

Whether it’s right or not, the only way for a potential employee to break that cycle is via side projects that they can show as experience.
