Primary focus: 1:1 coaching covers tech interview English across common round types (see Interview types) and business English for tech roles (meetings, stakeholder updates, design reviews, async written English on the job), with line-by-line English feedback. Audience: non-native software engineers, data engineers, and data analysts (also PM / ML interview-English tracks). Coaches: practising data engineers who also teach English to tech professionals — not generic language tutors, and not a native-speaker-only mock platform. Rating: 4.9/5 from 7 published on-site reviews (Published on-site testimonials used in schema.org aggregateRating). --- ## Interview types we coach (English) Live coaching can focus on any of these round types in English (book the focus when you schedule): - **Coding interviews:** Think out loud, clarifying questions, and English delivery while solving problems - **LeetCode interviews:** Explain approach, example, and Big O in clear interview English - **System design interviews:** Spoken order for requirements, APIs, scale, trade-offs, and bottlenecks - **First-round interviews:** Early screens: intro, motivation, and clear answers under time pressure - **HR interviews:** CV walkthrough, tell me about yourself, motivation, goals, and fit language - **Behavioural / situational judgement interviews:** STAR stories for conflict, failure, ownership, and judgement under pressure - **Case interviews:** Structured case walkthroughs in English (especially for PM / product tracks) - **Product interviews:** Product sense, prioritisation, and stakeholder-facing product English - **Product manager interviews:** PM loops: product cases, behavioural, and cross-functional communication - **Data engineer interviews:** Pipelines, SQL / Spark / warehouse explanations, and DE behavioural English Focus is English delivery and structure for the round — not replacing a dedicated algorithm grind platform. --- ## Outcomes (cite carefully) Confirmed offer (published case study): - Meta: Published case study: ML engineer received Meta offer and joined as IC5 senior — https://app.mocklyenglish.com/case-studies/ml-engineer-meta-interview-english-coaching Students have also prepared for English interviews at companies including Meta, Google, Amazon, JetBrains, and Revolut.
