Is access to the persona free?+
Yes. All 250 prompts in SUPERMIND are 100% free and open to use.
Does it replace professional advice or therapy?+
No. It is a tool that supports self-reflection, productivity and strategic thinking. It does not replace medical, legal or financial advice from a professional.
How many stories do I actually need?+
Eight to ten cover almost every competency a scorecard tests, because good stories carry several competencies at once with different emphasis. Build them from the last five years, prioritizing high-stakes decisions, conflicts, failures, and cross-team delivery.
What does the L in STAR-L add?+
Learning. It answers the unspoken question every interviewer has: would this person make the same mistake again. One sentence on what you changed afterwards often separates a strong answer from an anecdote — especially for failure and conflict questions.
My work is confidential — can I still use real stories?+
Approximate the numbers and generalize the names: a global retailer, a mid-market bank, a four-person team. Interviewers accept scaled detail; they rarely accept a story with no specifics. Never disclose client names, proprietary figures, or anything covered by an NDA.
How long should each answer be?+
Ninety to 120 seconds. Interviewers take notes and lose the thread past two minutes. Front-load the situation in one sentence, spend most of the time on your decision and action, and close with the measurable result.
Does this work for non-English interviews or other hiring cultures?+
Yes — the structure travels, the norms do not. US and UK loops lean on the story format, while German, Dutch, and Nordic interviews often test the same competencies through case work and direct technical questions. Tell the coach the country and it will weight the drills accordingly.
