“I could do the case in my head. Saying it clearly to a CEO-level interviewer was the part that broke.”
Starting Point
Hiking, weekends, Netflix — and a calendar of first rounds, case interviews, and behavioral screens. Coaching focused on enhancing stories and running cases out loud, the formats she was actually booking.
The Problem
She had a Warwick MBA, an AI product background in apps, and a post-grad visa clock in London. The next round was a case at CEO level. She could see the structure of the business problem. Spoken English did not keep up: stories ran long, cases lost the recommendation, and first-round behavioral answers felt thin. She wanted a job in three months — startup or bigger company — not a general English course.
What We Practised
Hours matched the loop: first-round behavioral, then case. Each mock was stopped for English — vague verbs, missing numbers, recommendations that never got said.
- PM case interviews (including CEO-level second rounds)
- Behavioral stories for product work
- First-round structure under a short visa timeline
- Language for metrics and trade-offs in app products
Useful references along the way: STAR interview framework, Pronouncing numbers and metrics.
The first mock is the same format we use in a free trial lesson — a real case or story, then English notes on that answer.
Before and After
Before coaching
- Case answers wandered before the recommendation
- Product stories lacked a visible outcome
- Three-month search pressure made every round expensive
- CEO-level case language felt heavier than peer chats
After coaching
- Spoken case order: clarify, structure, analyse, recommend
- A small bank of product STAR stories
- First-round intro that left time for questions
- Feedback on the same case, not a new topic every hour
The Result
She did not need another degree. She needed English that survived a second-round case and a first-round story in the same week. Coaching built that, on a three-month London search, without inventing a company offer the notes do not contain.
What She Would Do Differently
- Practise the case out loud before the second round is booked
- Keep five product stories, not twenty unfinished ones
- Treat CEO-level language as a register you can drill, not a personality
- Use the visa timeline as a constraint, not as panic
Why This Matters for PMs Job-Searching in London in a Second Language
PM loops mix storytelling and structured cases. International graduates often have the frameworks from school and still lose the recommendation in spoken English. That is a coaching problem, not an MBA problem.

Frequently Asked Questions
How do you practise PM case interviews in English?
Run a full case out loud, then review the language of the recommendation. Structure without a spoken ending still fails.
What should PMs prepare for a first-round screen?
A short career story, two product results, and time for the interviewer’s questions.
Is interview English different from MBA classroom English?
Yes. Classroom English can be exploratory. Interview English has to land a decision in a time box.
How long does PM interview English take?
Enough to bank stories and run several live cases. A three-month search is a reason to start mocks in week one.
Other engineers practising interview English
Mockly has helped me enormously in working toward my goals in Tech. Highly recommended.
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.
