>In those cases it makes sense to do whatever you need to do to stack interviews.

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.

>I’ve also not actually seen many cases where people schedule 10 interviews at once and actually get the full interview experience at every one of them. People get rejected at earlier stages of the interview process or they start pulling out if they realize the job isn’t a good fit.

sure, but even if you drop out partway through the process, the prep time remains the same, you're still blocking out time and scheduling, you're still occupied for a portion of the day, etc.

>So I understand your concern, but in my observation this pattern doesn’t really happen.

i have observed it often enough with my former students (and sometimes current ones) to be understanding of the people complaining about a 9 hour interview.

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.

Nobody doing long interviews is doing it blindly. It's because you're already passed some reasonable level of screening that mostly resembles a regular 45 minute type interview.
