Final answer:
An NCA and NDA are legal agreements used to protect a company's confidential information.
Step-by-step explanation:
Law
An NCA (Non-Compete Agreement) and NDA (Non-Disclosure Agreement) are legal documents used in the business world to protect a company's confidential information. In this case, the engineer is being asked to sign these agreements to prevent them from leaving and taking the company's ideas elsewhere.
The NCA restricts the engineer from working for a competitor or starting their own competing business for a certain period of time after leaving the company. The NDA, on the other hand, ensures that the engineer will not disclose any confidential information they have access to while working for the company.
