Why context matters?
1. Position description
This can be an official documents from your employer.
2. Update your current RESUME/CV and Key Selection Criteria
You must write your own resume/cv and ksc, this must be accurate and give as much details as you can, this is where CODEX reference most from.
3. Enable internet search tool
Further assess the job description and research industry standard practice, find relevant sources to support the mental framework, and common dilemma in the specific industry relevant to the role. Job descriptions sometimes can be too narrow for making a good debate on a topic.
The prompt
Use "mark down" style writing your prompt help codex understands better on your instructions
<Goal>
I have an upcoming interview for this role and would like help preparing for it.
<Context>
Please prepare me for the interview using the following documents and information: 1.The position description, which I uploaded earlier in the conversation. 2.My CV/RESUME, which you already have. 3.My key selection criteria response, which you also already have. Note: If you cannot access any of these documents, please ask me to provide them. Do not make assumptions or invent information.
<Instructions>
Prepare responses to four common interview questions: there are four interview themes that are common across most roles: time management, problem-solving, interpersonal skills, and motivation. Please review all available documents relating to me and this role, then prepare an answer to each of the following questions. Give the context first and remain the bullet point structure below.
1.1 Give me an example of a time when you worked under significant time pressure and within a limited timeframe. (eg: plan ahead, stay claim + good communication, proactively pivoting)
1.2 Give me an example of a time when you resolved an interpersonal conflict. (eg: separate people and issue, listening first)
1.3 Give me an example of a time when you resolved a workplace conflict. (eg: policy, correct channel, options vs sides)
1.4 Why do you want to work for this organisation?
(eg: researchers, education, social impact)
Identify expert mental models: based on all the documents you have about me, together with your research, identify three fundamental mental models commonly used by experts in this professional field and role. For each mental model:
2.1 Explain what it is.
2.2 Explain why it is important.
2.3 Show how experts use it to analyse problems.
2.4 Provide a practical example.
2.5 Identify the common mistakes beginners make when applying it.
Map the major areas of disagreement: based on all the documents you have about me, together with your research, identify three areas in which experts in this field fundamentally disagree. For each disagreement:
3.1 Clearly explain the central question.
3.2 Present the strongest argument from each side.
3.3 Identify the evidence supporting each position.
3.4 Explain the assumptions made by each side.
3.5 State whether the available sources suggest that one position is currently stronger.
3.6 Identify what further evidence would be needed to resolve the disagreement.
3.7 Cite the relevant uploaded sources.
Test whether I genuinely understand the knowledge: generate ten challenging questions designed to test whether someone genuinely understands the field, topic, and role in depth, rather than merely memorising facts. After I answer each question:
4.1 Evaluate my reasoning.
4.2 Explain what I understood correctly.
4.3 Identify any errors, gaps, or weak assumptions.
4.4 Explain what an expert-level answer should include.
4.5 Ask a follow-up question if my understanding is incomplete.
4.6 Do not reveal the complete answer before I have attempted the question.
Correction prompt: when my answer is incorrect or incomplete, explain precisely what is wrong and what I am missing. Then:
5.1 Identify the mistaken assumption. 5.2 Explain the correct reasoning step by step. 5.3 Provide an analogy or practical example. 5.4 Ask a new question that tests the same concept from a different perspective.
<Output Format>
Word document
First, provide all results in a clearly structured and professionally formatted Word document. Do not include sections 4 and 5 at this stage about the quiz, as I will not yet have answered the questions. These sections can instead be incorporated into the interactive site described below.
Interactive site Second, build an interactive site using @sites plugin. On the homepage, use /image gen skill to create a visual learning board, such as a mind-map. As I am a visual learner, please create this visual first and then incorporate it into the site.
