The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. She was a backend engineer in Europe. The gap was behavioral / STAR — not the technical content.

The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. She was a backend engineer in Europe. In the room, behavioral / STAR was what broke down.
Before coaching
After coaching
Practice matched the round she actually had to speak: behavioral / STAR. Each mock got notes on the same answer — where she paused, which words were vague, and where the structure broke.
Useful references along the way: STAR interview framework, What to expect in English interviews.
Gained clearer, more confident English for interviews. She could explain the work more clearly when questions got hard. That readiness was the goal — not a promised job offer.
A behavioral round asks you to remember an experience, pick the relevant details, structure a story, and still sound natural — all in a second language. You are choosing tenses, names, and numbers while the interviewer asks follow-ups. STAR is useful because it is a spoken order, not a script. Without that order, strong work disappears into a long, unfinished story.

She prepared for English-language interviews as a backend engineer. Written English was stronger than speaking under the clock.
The language of the round you will face — here, behavioral / STAR. Learn full sentences for that format, not a general business-English course.
That was the pattern here: written English was stronger than live answers. Practise behavioral / STAR out loud, with follow-ups, until retrieval is automatic.
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.
No. Clarity and structure are the bar. A small accent is fine if they can follow your decisions and numbers.

Written English was fine. Spoken answers stalled. See how one Backend Engineer from Russia practised STAR stories out loud.
