Why engineers practice tech interviews in English
Global hiring is now the default at most serious tech companies. The bar is no longer just whether your code works — panels score you on how clearly you explain trade-offs, narrate your thinking, and push back on requirements. For non-native English speakers, this is where strong engineers lose offers.
Mockly fills that gap. Our coaches are senior engineers and qualified ESL instructors who've sat on both sides of the table at global tech companies. You get focused 1:1 practice in the English half of the interview — with feedback on the exact phrasing that makes you sound senior.
Every round of a real tech interview — in English
Pick the round you're weakest at, or run a full loop. Sessions are tailored to the role and company you're targeting.
Coding Interviews in English
Practice LeetCode-style problems while narrating your approach. Your coach scores your phrasing, pacing, and how you explain trade-offs — not just your solution.
System Design Interviews in English
Run a full system design round out loud. Coaches focus on the connective English senior interviewers expect — hedging confidently, comparing options, and leading the discussion.
Behavioral Interviews in English
Build STAR stories that sound natural in English, not translated. We rewrite weak phrasing, cut filler, and rehearse answers that make hiring managers remember you.
Leadership Interviews in English
For senior, staff, and EM rounds. We calibrate your tone so panels hear ownership, scope, and impact at the level you're targeting.
Built for software engineers — not generic English students
Mockly is built for software engineers, data engineers, and data analysts — typically non-native English speakers — preparing for interviews at global tech companies. Every coach has shipped production code and run real interview loops. You won't sit through grammar drills. You'll get focused interview English practice that reflects how the round actually runs.
