Not a lecture and not a 1:1 lesson. A small group of engineers works a realistic technical scenario together, in English, with an instructor steering.

Every session is a situation you actually face at work.
Present and defend your technical decisions. Answer tough questions from peers.
Walk a room through a timeline, root cause, and remediation without hedging.
Give a crisp update, surface risks early, and ask for what you need.
Translate technical detail into commitments a non-technical stakeholder can act on.
Argue make-vs-buy, quantify a trade-off, and hold your position under scrutiny.
Evaluate a design end to end and say what breaks first at scale.
Everyone gets the context and prep materials in advance. You arrive with an opinion, not a blank page.
You are the Tech Lead, the SRE, the sceptic. Roles rotate week to week so you practise every seat at the table.
50 to 60 minutes of guided, unscripted conversation with 8 to 10 peers and one instructor.
The instructor and your peers give actionable notes. Recurring mistakes are logged from the recording so you can see your patterns.

The hard part of working in English is not grammar - it is holding your ground in a room full of other people. A one-to-one lesson cannot rehearse that. A cohort can: you practise disagreeing, interrupting, and being interrupted, with people at your level and in your field.
