Is this a mock interview?
No. CareerCorner writes a brief you read and then talk through with your coach: likely questions for each stage, from the posting, and stories from your own record to answer them with. Nobody plays the interviewer, and nothing grades your answers. If you want to rehearse out loud, your coach is a good partner for it, but the brief is the preparation, not a simulation.
Will it invent stories or figures?
No. Every story is grounded in exactly one achievement from the record you built with your coach, and it uses only the figures that appear there. It may rephrase for speaking out loud, it may not add, inflate, or combine. Each story shows the line in your record it came from, so you can check it yourself.
Where do the questions come from?
From the job description you saved with the role: its requirements, responsibilities, nice-to-haves, and what the company says about itself. Each stage gets questions tuned to what that stage tends to probe. Generic question-bank items are excluded on purpose. If a question would fit any job at any company, it does not belong in your brief.
Does it know which rounds this company runs?
Sometimes, and only from evidence. When the posting states how the loop runs, or candidates have reported it publicly, the brief says so and shows where it came from. When neither does, it says nothing about the rounds and prepares you for what each kind of round tends to probe: a recruiter screen, a hiring manager interview, a panel, an executive conversation. It never guesses an employer's loop from its industry.
Is it free to start?
Yes. Creating an account is free, and there is a free plan. Details are on the pricing page.
What does open alpha mean?
The core system is live and the edges are still moving. Today you get the coach, daily checks of company career pages, a read on how well each opening matches you with the reasoning shown, every role you are pursuing in one place, tailored résumés, and the prep brief. You will see it change as we build.
What happens to my data?
Your record, your saved roles and postings, and your prep briefs are private to your account and exportable. Nothing in a brief is sent to an employer. CareerCorner never applies anywhere on your behalf and never publishes your materials. The details live on the data security page.
Can I paste a posting and get a brief without an account?
No, and that is deliberate. Half of the brief comes from the posting, and the other half comes from your record, the one you build with your coach when you sign up. Without the record there are no stories, only questions, and questions without your own answers is the generic prep this page is about leaving behind. One onboarding conversation, then every role you save gets its own brief.
