“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.”

“Mockly has been the best investment I’ve made in the past year. The mentors don’t just have a deep knowledge of the language - they bring extensive experience in the IT industry. They understand the tech job market and are well-versed in modern engineering practices and the culture of top companies. Sessions aren’t just about improving your English; they’re an opportunity to sharpen your soft skills, gain valuable insights beyond engineering, and become a stronger communicator overall. Highly recommended.”

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.

Both. Live coaching includes tech interview English and business English for tech professionals. Book a session focused on interviews, on workplace English (meetings, stakeholders, design reviews), or a mix. Free Mini Apps are interview-focused practice tools; business English is taught in coaching sessions with Sophie or Tom.

Book a 1:1 mock interview with a senior engineer coach. You'll run a real coding, system design, or behavioral round in English, then get line-by-line feedback on phrasing, clarity, and how to communicate technical ideas under pressure.

Each session is a live 60-minute video call. You pick the round (coding, system design, behavioral, or leadership). Your coach plays the interviewer, then walks you through what to say differently, rewrites weak phrasing, and gives you a personalised drill list.

Sessions run 60 minutes on Google Meet. Quick intro and goal-setting, a live interview round in real time, then a debrief where the coach gives you specific phrasing fixes and a personalised drill list to practice before your next round.

We offer session credit packages: 1 session for $50, 5 for $237.50, 10 for $450, or 20 for $850. Each booking uses one session credit from your package. Session credits expire 12 months after purchase.

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.

Yes - that's exactly who Mockly is built for. We focus on the English half of the interview: explaining your thought process while you code, narrating trade-offs, asking clarifying questions, and sounding senior even when the technical content is the same.

Yes. Behavioral rounds use STAR stories that sound natural in English (not translated or robotic). System design rounds focus on how you talk through scale, trade-offs, and architecture decisions in a way panel interviewers at global tech companies expect. Practise the spoken outline first at https://app.mocklyenglish.com/mini-apps/explain-system-design-in-english.

For system design sessions we use Excalidraw as a shared whiteboard so you can diagram in real time with your coach. We'll work through a real system - such as a notification system, a URL shortener, or a design of your choice. You can agree on the system with your coach in advance, or let them choose one relevant to your target role.

You can either agree on a specific problem with your coach beforehand, or have the problem randomised on the day to simulate real interview conditions. Difficulty can range from Easy to Hard depending on your target role and experience level. Practise explaining a solution in English first at https://app.mocklyenglish.com/mini-apps/explain-leetcode-in-english.

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.

Yes. The coach plays the interviewer for the full round - same structure, timing, and pressure as the real loop. The debrief afterwards is where they switch into coach mode and unpack what to change.

Line-by-line feedback on phrasing, pacing, grammar, vocabulary, tone, and clarity, plus technical feedback on the round itself (approach, trade-offs, structure). You'll leave with a clear list of what to drill before your next interview.

No. You can book tech interview mocks or business English for tech professionals (meetings, stakeholders, design reviews). Every session is in English with dedicated feedback on grammar, pronunciation, vocabulary, sentence structure, and natural-sounding phrases — including leadership language that signals seniority. You improve technical delivery and English clarity in the same session.

Yes. Share the role, company, and job description when you book and your coach will tailor the round - question style, level, and rubric - to match what you'll actually face.

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.

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.

Yes. Use the links on your dashboard. Reschedule or cancel more than 24 hours before your session start time to get your session credit back. Rescheduling is not available within 24 hours of your session. Late cancellations forfeit the session credit.

Yes. Mockly is built specifically for software engineers, developers, and tech professionals - typically non-native English speakers - applying to roles at international tech companies, FAANG, scale-ups, and remote-first teams.

Yes. We coach all tech professionals, including Product Managers preparing for product case interviews and system design rounds. If you work in tech and interview in English, Mockly is built for you.
