[Get interview-ready with the free course](https://app.mocklyenglish.com/progress) FAQ ## Common questions What people ask before they book a free trial — who this is for, what the call covers, and how it differs from general English tutoring. ### Is this general English tutoring? No. Mockly is English coaching for people who already work in tech — tech interview English and business English for tech professionals — not travel English or casual conversation. In interview sessions you practise the rounds you will sit (HR screen, behavioural, live coding, system design) with a British engineer as the interviewer. In business-English sessions you practise meetings, stakeholder updates, design reviews, and clear explanations on the job. We correct the English that costs offers or slows you at work: thinking out loud, STAR ownership (“I” not “we”), trade-off language, and answers that sound senior instead of translated. ### Who is Mockly for? Non-native English speakers in tech targeting UK, US, EU, or remote roles: software engineers, data engineers, data analysts, PMs, ML, and engineering managers. If you can do the job in your own language but freeze, sound junior, or translate mid-sentence in interviews or meetings, this is built for you. Native speakers who only want extra LeetCode reps are a better fit for a coding-mock platform. Mockly is for interview English and business English for tech — the parts most prep ignores. ### What English level do I need to book a mock interview? B1+ conversational English is enough. You do not need to sound native, and we do not run accent-elimination drills. If you can hold a conversation, a coach can work with you: they will slow down, rewrite sentences you can actually say under pressure, and raise the bar as you get more fluent. If you cannot yet introduce your job in English, start with the free English check at https\://app.mocklyenglish.com/mini-apps/tech-interview-english-check, then the four-part intro and verb tenses, then book the trial. Sessions are 100% in English. ### I am not interviewing yet. Can I still start? Yes. Many students book coaching for business English at work first — meetings, stakeholder updates, design reviews — then switch to interview mocks when a loop appears. The free Interview English Course covers self-introduction, strengths and weaknesses, behavioural STAR, technical narration, and culture questions. Book the free 30-minute trial when you want a coach to hear you out loud and set a plan. Paid sessions do not require a subscription. ### What do you practise in coaching sessions? Two tracks, both in live 1:1 coaching. Tech interview English — common round types: coding interviews, LeetCode interviews, system design interviews, first-round interviews, HR interviews, behavioural / situational judgement interviews, case interviews, product interviews, product manager interviews, and data engineer interviews. Focus is English delivery and structure for the round you book. Business English for tech professionals: meetings, stakeholder updates, design reviews, status writing, and explaining technical work to non-engineers. You pick the focus when you book; the coach matches the role you are targeting. ### Is the trial really free? What happens on the call? Yes. It is a free 30-minute Google Meet with a coach. No card, no subscription, no automatic enrolment in Premium. You talk through the roles and companies you want, where English breaks down in interviews, and what is coming up on your calendar. The coach will hear you speak under a short interview-style prompt, then leave you with a concrete plan: which scripts to practise, whether you need behavioural vs system-design work first, and whether to book paid sessions. If you need more than 30 minutes, that is a paid 60-minute session — the trial is diagnostic, not a full mock. ### What is free, and what do I pay for? Free: the 30-minute trial class, the Interview English Course guides you can read without an account, and the mini apps at https\://app.mocklyenglish.com/mini-apps (English check, tell-me-about-yourself script, think out loud, LeetCode, system design). Case studies and the blog are also open. Paid: live 1:1 sessions (one session is $50; packs of 5, 10, or 20 cost less per session and last 12 months) and optional Premium for the full course at $9.99 a month or $59.99 a year. Premium does not include a coaching session and does not change the session price. You never have to subscribe to book a coach. ### Who are the coaches? Sophie and Tom — UK-based practising data engineers who teach in British English (BSc Mathematics, 8+ years teaching tech professionals each; thousands of lessons between them). Not generic language tutors. In interview sessions they play the interviewer first, then switch to coach: line-by-line phrasing, ownership language, and a drill list. Business-English sessions use the same coaches for meetings, stakeholder updates, and workplace clarity. You pick who you book with. ### How is this different from Preply, Cambly, or interviewing.io? General ESL apps (Preply, Cambly, iTalki) practise conversation. They will not run a Meta-style behavioural round or make you narrate a rate limiter in English. Coding-mock platforms (interviewing.io, Pramp) practise the algorithm; they rarely coach the sentences you say while you code, or the STAR story that follows. Mockly sits in the gap: a UK engineer who can hold the technical round and then rewrite how you said it. If your blocker is LeetCode difficulty, use a coding platform. If your blocker is sounding clear and senior in English, start here. ### Does this actually help people get offers? Coaching will not replace the technical bar — we do not claim that. What we do is stop English being the reason a strong engineer sounds junior or freezes on “tell me about a time.” The case studies hub has stories from non-native engineers, PMs, and analysts who used this work before loops at companies like Meta, Google, and Revolut: what blocked them (STAR, system-design narration, vocabulary) and what changed in live practice. Read a story close to your role, then book a trial to practise the same way. ### Do I need a subscription to book? No. Buy a single session ($50) or a package (5, 10, or 20) and book whenever you have a slot. The free 30-minute trial needs no purchase. Premium is optional: it unlocks the full course and does not change the session price. ### What time zones do coaches cover? Coaches are in the UK. You book in your own timezone via the calendar, so mornings in the Americas, European workdays, and evenings in Asia/CIS usually have openings. Pick any open slot for Sophie or Tom — you do not have to match UK office hours exactly. ### What if I don't see a time that works? Use the “Can't find the time?” link under the booking calendar to request a slot with your timezone and preferred time ranges (https\://app.mocklyenglish.com/request-time), or email contact\@mocklyenglish.com. You can also check the other coach's availability on the calendar. Prefer to study first?
