Last Saturday I met up with a senior of mine who’d been grinding away at their infrastructure interview prep. We chatted and he started walking me through what he’d been studying—different scenarios, real interview questions he’d encountered, the whole process.

I was honestly surprised by how realistic everything was. These weren’t textbook “what is TCP” questions. The scenarios had constraints, trade-offs, incomplete information. Just like actual industry production.

What hit me hardest was realizing how hard this actually is. I’d assumed infra interviews were about knowing your tools and protocols. But watching my senior work through these scenarios, I saw how much it demands—systems thinking under pressure, knowing what to ignore and what to investigate first. It’s not just knowledge. It’s judgment.
