Pick your company. Practise its exact rounds.

All courses →
  1. Pick your target company

    Each course starts with what that company's test actually asks, round by round.

  2. Learn the pattern

    Short lessons with worked answers, written for freshers, not for toppers.

  3. Practise in real editors

    Code, SQL, games and speaking tasks that look and time like the real round.

  4. Take timed mocks

    Full-length mocks show where you stand before the real test does.

Accenture Placement Prep is lifetime access. Cognizant GenC, Cognizant & Capgemini Games, and Communication Round Practice are 1 year from the date of purchase. All Access is sold for 3 months, 6 months, or lifetime, and an active All Access plan includes the company courses.

No. BuildUForward is an independent practice platform. Courses follow publicly reported test patterns and are not affiliated with or endorsed by any company.

No. The code editor, SQL playground, game simulators and speaking practice all run in your browser. Speaking practice needs your permission to use the microphone.

Accenture Placement Prep, Cognizant GenC, and Cognizant & Capgemini Games include a Telegram group for enrolled students, with the invite inside the course. An active All Access plan can open those courses, so it includes the same invites. Free practice does not include a Telegram group.
