The Gap Between Knowing and Explaining
Interviewers are not grading your accent. They need to follow your reasoning in English. She was a backend engineer in Moscow. Day-to-day work used Java. The next interviews were at Revolut, in English. In the room, vocabulary and clear pronunciation were what broke down.
Then vs Now
Before coaching
- Reached for words mid-answer and translated from another language
After coaching
- 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 for Revolut. 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.

What Other Engineers Can Learn
- 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 - including practice aimed at Revolut. 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.

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.
I’ve had the pleasure of practicing English with Mockly and I truly appreciate the progress I’ve made. I highly recommend their services to professionals in tech and beyond. I particularly enjoy the teaching style and the philosophy behind it: “If you enjoy the process, you’ll get it.” The personalized learning plans make every session practical and useful. Their hands-on knowledge and genuine interest in the world of technology will genuinely boost your English skills.
