This approach is logical and straightforward. The main flaw is that it treats all job opportunities equally. Life is not numbers, and the job you have or find will demand a significant portion of your life.

This means that you can spend more effort on getting the job that fits you the best and none or less effort for other opportunities.

Whether implicit or explicit, humans will short-change or sabotage job applications they don't want.
