How a Software Engineer From Poland Prepped for English Interviews
The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. He was a software engineer in Poland. The gap was vocabulary and pronunciation - not the technical content.
What this case shows
A software engineer from Poland trained interview vocabulary and pronunciation in English. Readiness - not a promised job - was the goal.

The Gap Between Knowing and Explaining
The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. He was a software engineer in Poland. In interviews he understood the question but searched for precise words, and pronunciation of key terms slowed his answers.
Before and After
Before coaching
- Pronunciation made metrics and names hard to follow.
- He reached for words mid-answer and translated from his first language.
After coaching
- He said numbers and key terms clearly enough to keep the story clear.
- He used a small set of precise terms instead of long approximations.
What We Worked On
Practice matched what he actually had to speak clearly: interview vocabulary and pronunciation. After each mock, he got notes on the same answer - where he paused, which words were vague, and where the wording broke.
- He replaced vague verbs with words interviewers actually hear (latency, trade-off, shipped).
- He practised saying numbers, metrics, and product names until they were clear.
- He built a short list of must-know words for this role - not a general vocabulary course.
- He repeated the same explanation until the terms came without translating.

What Other Engineers Can Learn
- Write the twenty 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 word searches and vague approximations.
What Changed
He gained clearer, more confident English for interviews. He 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.
