Or just do some work/exam in a controlled setting.
Talking to students in order to gauge their understanding is not as easy or reliable as some people make it out to be.
There are many students who are basically just useless when required to answer on the spot, some of whom likely to score top-of-the-class given an assignment and time to work on it alone (in a proctored setting).
And then there are students whom are very likable and swift to pick up on subtle signals the examiners might be giving of, and constantly adjusting course accordingly.
Grading objectively is extremely hard when doing oral exams. Especially when when you're doing them back-to-back for an entire workday, which is quite likely to happen if most examination is to be done in this way.
