Yeah, it's not about TDD, it's about having your testing be a non-automated checklist (without unit tests where useful)
Did you ask them about their practice? Did you ask how often they had to roll back deployments, or at least take a hit on something automated testing would have caught?
I asked them about their testing - turns out they were looking to have someone help them develop a way to test their software (so at least they want to do it).
I wish I'd asked them the two questions you listed at the end, they are much better questions than a bland "do you test?". They did break the build some times.
btw, I am glad no one asked the alternative to testing -- it would have been more a textbook on software development. <g>
