My Next Hop vs LeetCode for Network Engineer Interviews

LeetCode is genuinely the right tool for one specific thing: data-structures-and-algorithms coding rounds. If your loop includes a round where you're writing code against test cases under a timer, practising on LeetCode is the correct preparation, and no amount of network-engineering-specific practice substitutes for it.

Where LeetCode Is Genuinely the Right Tool

The mismatch is that most network and infrastructure engineering interview loops don't center on DS&A the way general software engineering loops do. The bulk of a network engineer or cloud network engineer panel is protocol mechanism, design trade-offs, live troubleshooting reasoning, and — increasingly — how clearly you can explain all of that out loud under follow-up. None of that is a coding-test format, and LeetCode has no mechanism to score any of it.

Why Most Infra Loops Aren't a Coding-Test Format

It's also not an all-or-nothing split by role. Some infra-adjacent tracks do include a lighter coding round alongside the infrastructure-specific ones — Meta's Production Engineer loop, for instance, is documented as including Python or C++ coding at a LeetCode medium/hard level alongside its networking and systems depth rounds. But for a pure network engineering track, network-specific scripting — parsing a routing table, automating a config change — tends to show up far more than classic algorithmic problems.

Where Coding Rounds Still Show Up in Infra-Adjacent Roles

If your target role and company genuinely includes a coding round, use LeetCode for that round specifically — it's the right tool for it. Use My Next Hop for everything else the loop is actually weighted toward: the protocol depth, the design reasoning, the live troubleshooting, and the delivery under a real panel that a coding platform was never built to score.
