In academia (my line of work) they’re required to have positions posted and open for a certain amount of time, interview a certain number of applicants, etc.
In theory, it’s for equal opportunity and finding the best person for the job.
In practice, it’s a waste of time, money, and hope.
Ibuprofen if I’m at work, but at home I usually take a short nap and have some coffee after, which works better for me.
