I've been advocating for a "coding interview" where both the interviewer _and_ interviewee draw some random question from leetcode or other problem bank, and try to work at it together.

This would show collaboration skills, and you can tell pretty easily how helpful the candidate is with his/her contributions, and whether you find there is an impedance mismatch somewhere.

It probably also maps more closely to the kinds of interactions you'd have after the person's been hired.

I think it would also help calibrate: if you can't figure it out, is it fair to expect the candidate to figure it out? Maybe it's just a hard problem!
