Frontend interviews at strong product companies are not just a test of how well you can code. They are a test of how clearly you can think, how calmly you can structure problems under pressure, and how well you understand tradeoffs before writing a single line of code.

Most candidates walk in underprepared, not because they lack ability, but because they prepared in the wrong direction. If you can code the solution but struggle to defend your decisions out loud, this is for you.

Start preparing the right way. Your next interview is closer than you think.
