Use an email address you control, keep your sign-in credentials private, and use your own account for saved practice. Temporary email addresses on Round’s blocked list cannot be used to sign up. Use only content your account is entitled to access. Do not bypass access controls, disrupt the service, or put credentials or confidential material in your practice work. Free access and trial Guests and signed-in Free accounts can use the questions and features available to their access level. Eligible accounts receive 14 days of trial access to Pro questions starting at email confirmation, limited to one trial per normalized email address. The trial is free, requires no payment card and ends automatically. Free access continues after trial access ends. Purchases, subscriptions and automatic charges are unavailable in this release. Your saved practice stays in your account after the trial. Access to the underlying Pro questions remains subject to eligibility. Practice and availability Round’s exercises, visible checks, reference solutions and timed sessions are for practice. Visible outcomes report the cases that ran and do not certify correctness or predict interview results. Round timed practice uses a fixed server deadline that continues through reloads and navigation. Completion is self-reported. Timed practice is Round’s format and is not an employer assessment or a proctored exam. On supported questions, Python and JavaScript Run execute in your browser. Hosted Java and C++ execution is disabled in this Free release. You can still edit code for those languages where an editor is available. Guest work stays in the browser until you choose to transfer it, and signed-in work can sync to your account. Export work you want to keep. Features and question availability can change, and Round can be temporarily unavailable.
