You know how to do the job. The difficult part is explaining it in English when an interviewer is watching. He was a product manager in United Kingdom. The gap was behavioral / STAR — not the technical content.

Practice matched the round he actually had to speak: behavioral / STAR for Revolut. Each mock got notes on the same answer — where he paused, which words were vague, and where the structure broke.

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.
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.

Mockly has helped me enormously in working toward my goals in Tech. Highly recommended.

Mockly knows what it takes to get hired. The preparation covers behavioral, algorithm, and system design interviews thoroughly — with real expertise in the STAR method, LeetCode, and Alex Xu’s system design frameworks. And when it comes to English and communication skills, the native-speaking mentors make all the difference.
The language of the round you will face — here, behavioral / STAR. Learn full sentences for that format, not a general business-English course.
Lead with the result, then the action you took. Cut the long setup. Practise follow-ups on the same story so you do not invent a new timeline each time.
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.
That was the pattern here: written English was stronger than live answers. Practise behavioral / STAR out loud, with follow-ups, until retrieval is automatic.
A Croatian PM was targeting Revolut. The gap was STAR stories in English — not the technical work. Here's what they practised.
Explaining STAR stories while an interviewer watched was the hurdle. This PM trained that skill for Revolut — no offer claimed.
