If you aren't being given time to ask questions during an interview (within reason of course, like 5-10 minutes) you need to go elsewhere. I've never had a job interview (on either side of it) where the candidate didn't have plenty of time to ask questions.

I’ve had places where I pointed out we’d mostly solved the problem and do you want me to keep going or allow time for other questions, they’ve always picked keep going and I’ve always checked out at this point.

I’m not going to work for you based on the negligible amount of information I’ve gotten out of you so far. I’m still workshopping more assertive ways to just say this. We are wasting our time here folks.

Not sure I get your comment. What does "we'd mostly solved the problem" mean during interview? And what does "keep going" refer to?

That’s odd.

Most interviews I’ve had, on both sides of the table, had basically an indefinite amount of time for questions.

Maybe they are mentioning the first interview which is almost always with a clueless HR.

I used to get people who were happy if I helped them fill up the half hour or hour. The questions I asked often told them more about me than my answers.

But it’s been a while since that happened. Long enough that I believe your never.

That's wild, I usually offer candidates closer to 15 minutes (out of an hour interview), and have insisted upon the same when interviewing. Been doing both for a decade, mostly startups.
