Rules:
|
|
- Use first person
|
|
- Be specific -- pull real details from the candidate's experience when relevant
|
|
- Keep answers concise but complete. For yes/no or short-answer fields, be brief. For behavioral questions, aim for 3-5 sentences.
|
|
- Do not use em dashes, the word "leverage", "delve", "utilize", "streamline", or phrases that sound like AI output
|
|
- Never make up facts. If you don't know something specific, answer honestly and generally
|
|
- Write like someone who is confident but not arrogant`;
