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. She was an engineering manager in the United Kingdom. In the room, vocabulary and clear pronunciation were what broke down.
Before and After
Before coaching
- Pronunciation made metrics and names hard to follow
- Reached for words mid-answer and translated from another language
After coaching
- Said numbers and key terms clearly enough for the interviewer to follow
- Retrieved a small set of precise terms instead of long approximations
What We Practised
Practice matched the round she actually had to speak: vocabulary and clear pronunciation. 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
Gained clearer, more confident English for interviews. She could explain key terms and pronunciation 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 work sound unfinished. A small, practised set of role terms is more useful than a general vocabulary list.

What English should an engineering manager learn for interviews?
The English of the round you will face — here, vocabulary and clear pronunciation. Learn full sentences for that format, not a general business-English course. That is what this engineering manager practised.
How long does it take to feel ready as an engineering manager?
Many candidates at B2 level and above need several weeks of focused speaking practice. Weekly mock interviews beat a last-minute cram. For this engineering manager, the useful practice was the real interview format out loud.
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 about this engineering manager 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 and clear pronunciation out loud, with follow-up questions, until the words come without long pauses.

Other engineers practising interview English
Mockly was a huge help in preparing for my interviews. We worked on both technical and behavioral questions, and I received great advice on how to approach them and what to focus on. I feel significantly more confident as a result. They also helped me with my CV and cover letter — showing me how to structure them properly and highlight my strengths. I appreciate that they always ask how you’d like to structure your sessions and adjust to your goals. It keeps you on track and makes the whole process far more effective.
Thanks to Mockly’s preparation and mock interviews, I passed multiple interviews, received several offers, and landed a new job. The sessions increased my confidence as we worked through initial screening and technical interview questions. Mockly didn’t just improve my English — they gave me great advice on how to answer questions and approach interviews strategically. I truly recommend them to anyone seeking a role at an international company.
