Yeah - I was aware of the "heap" as in "stack vs heap". Though I could not explain, without looking it up, what the difference is between values being put on the stack or the heap.

Now, of course, after reading about it in the linked article, I looked it up and now I have an understanding of it.

But I wonder how much this will be taken into account during an interview. I could, from the technology I'm working with, explain what the pitfalls of an async/await-pattern are, or what the difference between the logical and the visual tree in WPF is.

I wonder if you loose some knowledge on the way while working in a certain domain for a long time, and if that's a bad thing per se.
