28:00 The problem with TDD is that it is very difficult to come up with a perfect public API and do the implementation later, because when you start working on that, you will realize, that the API does not fit. Often times, people stick to the API and continue to work with a "wrong" business model, just not to break the API promises. TDD is not useless, you should learn and apply it on at least one of your projects. It will teach you to think about potential pitfalls in the future, but once you understand that, TDD will just slow you down.
TDD is just one of the tool in the toolbox - I don't always do it. However, hardcore TDD practice definitely helped in developing my intuition during my early days
This is a really good talk, so we went ahead and featured it in the latest issue of 💥Tech Talks Weekly. Congrats Grzegorz 👏
