What makes a good form? Walk me through the principles you follow.
What the interviewer wants to hear
- Ask only what is needed
- Clear visible labels, logical order, single column
- Right input types and helpful defaults
- Helpful inline validation and error messages
- Accessible: labels, keyboard, error announcements
Model answer
First I question every field: if we do not need it now, we do not ask. Then I group questions logically and use a single column, which is faster to scan. Every field has a visible label above it, not a placeholder that disappears, with hints for format where needed. I pick the right input type, like a numeric keyboard for phone numbers and date pickers where they help, and I support autofill and password managers. Validation happens when the user leaves a field, and error messages say what went wrong and how to fix it, in plain words, next to the field. For long forms, an error summary after submit links to each problem. All of this must work with a keyboard and screen readers, and finally I test the form with users and watch field-level drop-off in analytics.
