One additional point of data about caring about exit interviews: I have been in a team where an excellent engineer left for a different company. He came back about one year later a more senior role, and was instrumental to the company success in the following years.

There have been many studies on interviewing and what works. Instead this is another anecdote fill article with no indication of data - even though it implies there should be some.
