Strong engineers still stall when they have to think and speak English at the same time. She was a engineering manager in London. The next interviews were at Yandex, in English. In the room, vocabulary & pronunciation was what broke down.
Before coaching
After coaching
Practice matched the round she actually had to speak: vocabulary & pronunciation for Yandex. 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, Pronouncing numbers and metrics.
Prepared English for a leadership / promotion path. She could explain the work more clearly when questions got hard. That readiness was the goal — not a promised job offer.
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.

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.

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.
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.
Create your Mockly account →The language of the round you will face — here, vocabulary & pronunciation. Learn full sentences for that format, not a general business-English course.
Practise the real format out loud, especially vocabulary & pronunciation. Get notes on pauses and vague wording after each mock — not only on the technical content.
Many B2+ candidates need several weeks of focused, spoken practice. Weekly mocks beat a last-minute cram.
Yes. Interviewers need to follow your reasoning. A clear structure and the right words matter more than sounding native. This case study is about that gap — not about erasing an accent.
A German Backend Engineer was targeting Yandex. The gap was system-design answers in English — not the technical work. Here's what they practised.
An ML Engineer from Germany prepped Yandex's behavioral rounds in English: what stalled, what they practised, what changed.
