The Gap Between Knowing and Explaining
Strong engineers still stall when they have to think and speak English at the same time. He was a software engineer in Singapore. In the room, system design was what broke down.
What We Practised
Practice matched the round he actually had to speak: system design. Each mock interview included notes on the same answer - where he paused, which words were vague, and where the structure broke.
- Practised stating the requirements in English before naming any services or components.
- Used the same spoken order every time: scope, then main components, then bottlenecks, then trade-offs.
- Practised explaining design trade-offs out loud, not only drawing boxes on a board.
- Worked on saying metrics in full English sentences - for example latency, load, and cost.
- Described the architecture in English without stopping to translate each sentence in his head.

Why System Design Is Difficult in English
System design is a thirty-to-forty-five-minute spoken explanation. You must order the components, defend trade-offs, handle follow-up questions, and keep the 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 clear in a second language.

After the Coaching
Gained clearer, more confident English for interviews. He could explain system-design answers more clearly when questions got hard. That readiness was the goal - not a promised job offer.
What to Practise
- State the scope in English before you name any services.
- Use one spoken order every time: requirements, then scale, then architecture, then bottlenecks, then trade-offs.
- Practise saying metrics such as latency, queries per second, and storage in full sentences.
- Name at least one trade-off out loud, even when you are sure about the design.
- Record a fifteen-minute design walkthrough and listen only for jumps and unfinished sentences.
