Gas pitfalls juniors mention — what interviewers actually assess

I keep throwing buzzwords in gas discussions because I’m afraid silence will make me look clueless. But it backfires. Interviewers push deeper and I run out of substance. I want to answer gas questions like a responsible engineer, not a tips machine.

What are the pitfalls worth mentioning that prove real thinking? And how do you avoid sounding like you memorized a checklist instead of understanding trade-offs?

Concrete phrasing examples would help a lot.
