Show HN: Fronteer – Real front end interview challenges (not just LeetCode)

[CGamble26]

I’ve been talking to frontend engineers about how they prep for interviews, and the answer is usually: “LeetCode — even though it doesn’t cover what I actually get asked.”

So I built Fronteer: a platform focused only on real-world frontend interview prep — React, CSS, async JS, layout, and system design.

It’s early, but I’d love feedback from anyone who’s hired or prepped as a frontend dev. I’m validating whether this even should exist.
