I'm a hiring manager. I don't make people do offline stuff. I do EVERYTHING IN MY POWER to make certain they are not doing more than a phone screen w/HR (absolutely mandated by the company or I wouldn't allow it) and meet with the team. For Senior Managers+, I do require one extra interview with other teams because they'll be interfacing. So, max investment is 2.25h. If we cannot make a decision from that investment, we have failed as evaluators.

Being that I have lost exactly 3 folks over my 15y as a leader and only one of those due to performance (within 6 months of starting as a leader) I think anyone should be able to do this.
