Before you start

What does it cost?

The basic trainers, the first lesson of every course, the daily plan and one AI interview a week are free. Pro opens everything for $4.99 a month or $39.99 a year, and starts with 7 free days. With a university email, Pro costs half.

Are these real questions from the firms?

No. We write our own problems in the style each firm tests, based on public descriptions of its process, and label them as typical of that firm.

Do I need an account?

No. The basic trainers open for guests. When you sign up, the progress on this device moves into your account.
