Strong coders lose offers in HR rounds to weaker coders who communicate clearly. Fluency is a skill, not a talent — 30 minutes daily for 30 days moves it visibly.
The daily 30 minutes
- 10 min — shadow speaking: play a tech YouTube video (Fireship, freeCodeCamp), pause each sentence, repeat it aloud copying rhythm. This rewires mouth-speed, not grammar theory
- 10 min — explain code aloud: take any function you wrote and explain it to an empty room: "This function takes an array, filters out…" — this IS the interview skill
- 10 min — record yourself answering one HR question on your phone. Listen. Cringe. Improve. Fastest feedback loop that exists
Kill the filler habit
"Basically", "actually", "like" — replace with a silent pause. Pauses read as confidence; fillers read as doubt.
Technical vocabulary bank
Practice saying smoothly: "iterate over", "edge case", "time complexity", "the trade-off is", "I'd refactor this by". Interviews reuse ~50 phrases — collect them from mock interview videos.
Weekly checkpoint
One mock interview with a friend on video call, English only, 20 minutes. By week 4 the difference is audible. Your accent is fine — clarity and structure are what get graded.
