These numbers are probably the least valuable numbers you will see on Hacker News today. Almost every one is an exception to an anecdote, and an anecdote with exceptions.<p>Things like "90 - the number of days a role should stay open
90 days is the industry standard time-to-hire metric."<p>So is 90 days the average in this industry? Do you want to be average? Is it really your goal to do things they same way all of your competitors do? A role should stay open EXACTLY as long as it needs to. Putting artificial numbers in front of it and acting like there is some magic 'best practice' is ridiculous. There may be some jobs that take longer, and some that take much much less. The last thing you need to do is sit around answering questions like "Why is this taking longer than the industry standard?".<p>If you really need to manage by following a list of 'numbers' you are a fantastic illustration of why there can be so much differentiation among companies. Great companies can build great successes on the back of thoughtless process.
