Ruby / Rails
Ruby and Rails drills that mirror what backend interviewers actually probe — blocks vs procs vs lambdas, the object model and metaprogramming, ActiveRecord and the N+1 trap, migrations, routing, background jobs with Sidekiq, RSpec, and security. From fresher syntax to staff-level performance reasoning, all at your pace.

Why this matters at interviews
Real interviewers don’t just check if you know the syntax — they probe whether you’ve used the concept under production pressure. Our drills mirror that. Adaptive difficulty, named anti-patterns called out as you go, and a senior-staff voice that teaches the production vocabulary rather than dumbing it down.
