> right, people will do it, but then they'll complain on a forum about having to spend 60+ hours (with prep time) for a handful of interviews with no guarantee of a position and i think that's a fair complaint to make.

This is an acceptable filter for me on both sides of the table.

You are interviewing them as much as they are interviewing you. Where you work should be a major life decision. These are the humans and craft you’re going to spend your time with/on for 40+ hours a week for years. You aren’t going to get a glimmer of understanding of the culture, people, and work in a single 45 minute interview (short of major red flags).

If all you’re doing is looking for a job, any job, I get this sentiment - and the other side of the table needs to be looking for a butt in a seat, any butt, and then these shotgun interviews work.

But if you’re optimizing for career and quality of life, having an extended diligence process is a pro, not a con. Especially since that means the team you’re joining has passed muster in the same diligence process when they were hired.

A strong diligence process signals the company takes who they hire seriously - and that the people who work there take where they work seriously.
