The Interview Problem
Interviewers are not grading your accent. They need to follow your reasoning in English. She was a software engineer in Europe. Day-to-day work used AWS. The next interviews were at Amazon, in English. In the room, vocabulary & pronunciation was what broke down.
Then vs Now
Before coaching
- Pronunciation made metrics and names hard to follow
- Reached for words mid-answer and translated from a first language
After coaching
- Said numbers and key terms clearly enough to keep the thread
- Retrieved a small set of precise terms instead of long approximations
What We Practised
Practice matched the round she actually had to speak: vocabulary & pronunciation for Amazon. 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 retrieval list 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.

What English should a software engineer learn for interviews?
The language of the round you will face — here, vocabulary & pronunciation. Learn full sentences for that format, not a general business-English course.
How long does it take to feel ready as a software engineer?
Many B2+ candidates need several weeks of focused, spoken practice. Weekly mocks beat a last-minute cram.
Can I pass a tech interview if my English isn't fluent?
Yes. Interviewers need to follow your reasoning. A clear structure and the right words matter more than sounding native. This case study is about that gap — not about erasing an accent.
What if I understand English but struggle to speak in interviews?
That was the pattern here: written English was stronger than live answers. Practise vocabulary & pronunciation out loud, with follow-ups, until retrieval is automatic.
