While at university, we had one professor who would assess student assignment papers after conducting an interview. It would take him 5-10 minutes per person and cheaters really did get caught out. It is a common practice in some universities and it's very hard to cheat when being asked questions in person. It can be done online, as long as the identity of the person can be verified. Takes a lot longer and is a lot more engaging that written tests, but it works.

I wonder how he handles foreign students who feign language difficulty when convenient. From what I've seen, such cheaters tend to get away with it.

There was this case of a foreign student who submitted a perfectly written paper, obviously copy/pasted from some websites. At the interview, he could not answer any questions properly, and that made it even more clear that he could not have written the marketing-type paragraphs. I think he did just pass anyway, but that’s a different story - the university tended to let international students pass easier sometimes.
