How a British Engineering Manager Built English Fluency for Yandex
Strong engineers still stall when they have to think and speak English at the same time. She was an engineering manager in London. The gap was vocabulary and clear pronunciation - not the technical content.

The Gap Between Knowing and Explaining
Strong engineers still stall when they have to think and speak English at the same time. She was an engineering manager in London. The next interviews were at Yandex, in English. In the room, vocabulary and clear pronunciation were what broke down.
Then vs Now
Before coaching
- Pronunciation made metrics and names hard to follow
After coaching
- Said numbers and key terms clearly enough for the interviewer to follow
What We Practised
Practice matched the round she actually had to speak: vocabulary and clear pronunciation for Yandex. Each mock interview included notes on the same answer - where she paused, which words were vague, and where the structure broke.
- Replaced vague verbs with the precise words interviewers expect, such as latency, trade-off, and shipped.
- Practised saying numbers, metrics, and product names until they were easy to hear.
- Built a short list of words for this role - not a general vocabulary course.
- Repeated the same explanation until the key terms came without translating from another language.
Useful references along the way: STAR interview framework, Pronouncing numbers and metrics.
What to Practise
- Write the twenty terms you will actually say in this interview round. Practise them in full sentences.
- Say numbers and names out loud until they are clear without slowing down.
- Stop translating mid-sentence. If the precise word is missing, give a short definition and continue.
- Record one answer and listen only for word searches and long approximations.
What Changed
Prepared English for a leadership path. She could say numbers, metrics, and key terms clearly enough for a Yandex-style interview. 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 work sound unfinished. A small, practised set of role terms is more useful than a general vocabulary list.
