Money doesn't cleanly convert into time.

Having juniors and mid-levels is about being able to promote an existing mid-level that knows the team and the system, with zero downtime. It's much easier to replace a junior than a senior because of the lower expectations and risk.

Furthermore, a lot of companies are struggling to hire right now because the market conditions creates a flood of applications and its quite hard to discern who's a waste of time or not which leads to hiring processes taking longer.

Yeah but the point of this post is that it makes an assumption that your company doesn't have mid-levels or juniors.

Hiring is the most important function in any company, full stop.

If they aren't good at hiring, well then they shouldn't be running a company. There are no excuses. If HR aren't up to the task, then they should be replaced, and so on up to the level of the CEO, until whatever incompetence has been flushed out. Shareholders have to demand this.

A company not being able to hire is just as ridiculous as a restaurant not being able to serve food.

If they are receiving a flood of applications which is hard to sift through, they are already doing everything wrong. Shareholders have to nuke these kind of people.
