The Interview Problem
Strong engineers still stall when they have to think and speak English at the same time. She was a software engineer in Europe. In the room, vocabulary and pronunciation were what broke down.
Then vs Now
Before coaching
- Reached for words mid-answer and translated from a first language.
After coaching
- Used a small set of precise terms instead of long, vague descriptions.
What We Worked On
Practice matched the round she actually had to speak: vocabulary & pronunciation. Each mock got notes on the same answer - where she paused, which words were vague, and where the structure broke.
- Replaced vague verbs with the words interviewers actually hear (latency, trade-off, shipped).
- Practised saying numbers, metrics, and product names until they were clear.
- Built a short list of words to practise for this role - not a general vocabulary course.
- Repeated the same explanation until the terms came without translating.

What Other Engineers Can Learn
- Write the 20 terms you will actually say in this round. Practise them in full sentences.
- Say numbers and names out loud until they are clear without slowing down.
- Stop translating. If the precise word is missing, use a short definition and move on.
- Record one answer and listen only for searches and approximations.
The Difference
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.
Why Vocabulary Breaks Interviews in English
You can know the work and still lose the round while searching for a word. Interviewers follow a sequence. Long pauses and vague verbs make strong engineering sound unfinished. A small, practised set of role terms is more useful than a general vocabulary list.
