Interview English: A Software Engineer Case Study
The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. He was a software engineer in the Netherlands. The gap was vocabulary and pronunciation - not the technical content.
What this case shows
A software engineer in the Netherlands knew the work. Live English - finding and saying the right technical words - was where interviews stalled.

The Interview Problem
The CV shows the work. The interview asks you to explain it in English, live, without stopping to translate. He was a software engineer in the Netherlands. In interviews he understood the question but searched for precise words, and pronunciation of key terms slowed his answers.
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 Practised
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 system 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.

What Other Engineers Can Learn
- 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.
After the Coaching
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.

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.
