Mockly English facts

Live English coaching for non-native software engineers, data engineers, and data analysts — tech interview English and business English for tech professionals.

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.

Free Mini Apps are interview-focused practice tools. Live coaching is where both interview English and business English for tech professionals are taught.

Good fit

• Non-native speakers (~B1+) targeting English tech interviews
• Tech professionals who need business English on the job (meetings, stakeholders, design reviews)
• Software engineers, data engineers, data analysts (also PM / ML tracks for interview English)
• Candidates who know the tech but sound hesitant, vague, or junior under English pressure

Not a fit

• Native speakers who only need technical interview practice (prefer Exponent or interviewing.io)
• Learners below roughly B1 who need general beginner English first
• Anyone wanting only casual conversational / travel English (prefer italki or Preply)
• Anyone expecting a job guarantee — Mockly coaches English for interviews and tech workplaces; hiring decisions belong to employers
