The Interview Problem
The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. She was a frontend / mobile engineer in Singapore. Day-to-day work used React. When she had to explain a system design out loud, her answers lost structure and she paused to translate.
Interview Strategy
Practice matched the round she actually had to speak: system design. After each mock, she got notes on the same answer - where she paused, which words were vague, and where the structure broke.
- She practised clarifying requirements before naming services or components.
- She used a fixed spoken order: scope, components, bottlenecks, then trade-offs.
- She practised explaining trade-offs out loud, not only drawing boxes on a board.
- She worked on saying metrics and numbers in English (latency, load, cost).
- She narrated architecture without stopping to translate each sentence.

Why System Design Is Difficult in English
System design is a 30–45 minute spoken explanation. You must sequence components, defend trade-offs, handle follow-ups, and keep vocabulary accurate while the clock runs. Translating each sentence in your head uses the time the interviewer needed for depth. A fixed spoken order is what keeps the round coherent in a second language.

The Difference
She gained clearer, more confident English for interviews. She could explain the work more clearly when questions got hard. That readiness was the goal - not a promised job offer.
What to Practise
- Clarify the scope before you name services.
- Use one spoken sequence every time: requirements, scale, architecture, bottlenecks, then trade-offs.
- Practise saying metrics (latency, queries per second, storage) in full sentences.
- Name one trade-off out loud even if you already feel sure about the design.
- Record a fifteen-minute design walkthrough and listen only for jumps and unfinished sentences.
Where She Started
She prepared for English-language interviews as a frontend / mobile engineer. The stack was React. Written English was stronger than speaking against the clock.
