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 & pronunciation — not the technical content.

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 the room, vocabulary & pronunciation was what broke down.

Before and After

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 Worked On

Practice matched the round he actually had to speak: vocabulary & pronunciation. Each mock got notes on the same answer — where he 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.

What Changed

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.

Frequently Asked Questions

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.

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.

Should I practise technical interviews in English?

If the real loop is in English, yes. Silent LeetCode or notes in your first language do not train the round the interviewer will hear.

Do I need to sound like a native speaker?

No. Clarity and structure are the bar. A small accent is fine if they can follow your decisions and numbers.
