Pause briefly to choose dimensions before generating more ideas.

Overlap usually happens when you brainstorm examples before deciding how the space is organized.

Group the first few ideas, identify the missing dimension, and then generate ideas from that missing area.

Practice two-stage brainstorming: structure first for a few seconds, then populate the branches. You can also use this CaseBasix guide for a structured review.

No reply to a thank-you is normal in my experience. I would only message again when you have a real reason.

I had a different experience: the interviewer did not seem to care about the label, only whether I could explain the logic.

This is where live mocks helped more than solo prep for me because you get used to the awkward moment itself.
