Signing NDAs and confidentiality agreements are commonplace these days. These allow them to ensure the integrity of their company remains intact and that you are willing to abide by their rules of conduct as an employee. According to the standards of business conduct for employees, they require specific commitments, which they detail as; "we don't reveal or trade on inside information, we follow our media policy, we protect confidential information, we maintain accurate books and records, we are careful with gifts and hospitality, and we avoid conflicts of interest." When asked this question, express your willingness, and describe your familiarity with their business conduct for employees while assuring them of your character.
