How a Russian-Speaking Engineer Prepped for a Big Tech Interview
The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. He was a product manager in Germany. The gap was vocabulary and 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 product manager in Germany. The team often spoke Russian, so live English was not daily practice. In interviews he searched for product words mid-sentence, and pronunciation of metrics and names slowed him down.
Then vs Now
Before coaching
- Reached for words mid-answer and translated from a first language.
After coaching
- 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.
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 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.
The Difference
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.

Starting Point
He prepared for English-language interviews as a product manager. Homework between classes locked in phrases. Written English was stronger than speaking against the clock.

Frequently Asked Questions
What English should a product manager learn for interviews?
Learn the words and sentences you will actually say in the round. For him, that meant product vocabulary and clear pronunciation in full answers — not a general vocabulary list.
Do I need to sound like a native speaker?
No. Clarity and structure matter most. A light accent is fine if they can follow your decisions and numbers.
How do you prepare for a product manager interview in English?
Practise the real format out loud, with special attention to the words you stumble on. Get notes on pauses and vague wording after each mock.
How long does it take to feel ready as a product manager?
This plan ran about eight weeks. Keep mocks weekly so the language stays automatic.
Practise the vocabulary you will actually say in the interview
No card required. Start with a 7-day free trial — a lesson, a mock interview, or both.

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.
