Common Frontend Interview Mistakes
Most rejections aren't about not knowing the answer — they're about how the answer is delivered. Here are the mistakes that quietly cost offers.
In the technical rounds
Rambling instead of leading with a one-line answer; not clarifying requirements before coding; ignoring edge cases (loading/empty/error states); mutating state in React; using array index as a key on dynamic lists; and over-engineering a simple problem. Structure your answer, then go deep.
In the behavioural round
Vague stories with no result, saying 'we' instead of 'I', trashing a past employer, and having no genuine 'why this company' answer. Use STAR, quantify outcomes, and stay positive.

- What's the single biggest mistake?
- Not explaining your reasoning. Interviewers score how you think — a correct answer with no explanation is weaker than a structured, well-reasoned one.
- How do I recover from a wrong answer?
- Acknowledge it, reason out loud, and correct course. Composure and honesty score higher than pretending.
