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 Berlin. In interviews she could discuss code more easily than broader work topics — stakeholder updates, trade-offs for non-engineers, and confident small talk that still sounded professional.

After coaching
Practice matched the English she actually had to speak: business English in interview-style conversations. After each mock, she got notes on the same answer — where she paused, which words were vague, and where the structure broke.

She improved speaking confidence toward interview and IELTS goals. She could explain the work more clearly when questions got hard. That readiness was the goal — not a promised job offer.
Backend Engineers interviewing in English must explain work and handle follow-ups in real time. Grammar study alone does not train that. Practising the actual round out loud — business English — is what makes the next interviewer able to follow you.

That was her pattern: written English was stronger than live answers. Practise interview conversations out loud until follow-up questions no longer cause long pauses.
Yes, if the real interviews are in English. Quiet practice or notes in your first language do not train the round the interviewer will hear.
No. Clarity and structure matter most. A light accent is fine if they can follow your decisions and explanations.

Mockly has been the best investment I’ve made in the past year. The mentors don’t just have a deep knowledge of the language — they bring extensive experience in the IT industry. They understand the tech job market and are well-versed in modern engineering practices and the culture of top companies. Sessions aren’t just about improving your English; they’re an opportunity to sharpen your soft skills, gain valuable insights beyond engineering, and become a stronger communicator overall. Highly recommended.

Mockly’s approach is genuinely personalized — they use a variety of methods tailored to your specific needs. With their help, I improved my spoken English and prepared thoroughly for behavioral interview questions across different companies. This not only helped me refine my stories grammatically but also ensured I was using the right examples to answer specific questions effectively.
