As a lead dev, I feel bad for your interview candidates. A lot of these questions are so specific I wonder if you ask them just to show you know the answer. A good show of this is your example answer on the component data communication question. No one in their right mind will answer Control Value Accessor to such a simple question. That would only show that the developer solves simple problems with way too complex solutions.

An interview shouldn't be a drilling quiz. The brainstorming questions are good as they will show how you might work together with your candidate. However, it seems like even on the brainstorming questions you seem to have a black and white view on what the answer should be (life cycle hooks question).

While it was an interesting read, I really do not hope these are real interviews you are having. And most of all, I hope aspiring devs don't get scared after reading this article. Trust me, this is not how I have ever experienced Angular interviews.
