BUSHRA · INTERVIEWER
Walk me through how you'd design a URL shortener. Start with the read/write path — what happens when someone creates a short link, and what happens when one is visited?
YOU
On write, I'd generate a unique key — base62 of an auto-increment ID — and store the key-to-URL mapping. On read, I look up the key and 301 to the long URL, fronted by a cache for hot links.
FEEDBACK
78/ 100
- Clear read/write split and a cache for hot links — strong instinct.
- A 301 is permanently cached — how would that affect click analytics?
Bushra remembers: last session you skipped capacity estimates — so this round probed them.
This is a real example. Your interview is live, spoken, and adapts to you.
