Conventional job interviews are bad from the viewpoint of the interviewees is that even though the function is to hire somebody, the process is fundamentally a rejection process. It is in everybody's interest to disrupt this process.

One of the greatest job interview hacks is this:

Imagine yourself as a consultant who is there to solve a problem for the business right there in the job interview and you can tell them that is your goal. Take advantage of "do you have any questions for us?" to probe deeply on a problem they have: sometimes you can get people talking for hours and get a lot of information.

This works best at small firms, say 20 employees, where you can talk to the principals. Big companies like Google have a structured hiring process precisely to defeat this and other interview hacks.
