At this point, you can probably already recognize this as a technical question. This is obvious because it is both asking you for a definition and to discuss the differences in these terms and how they are used in your profession. Keep in mind that technical questions are best answered directly and briefly. The interviewer will ask you additional questions if they need more information or want to explore this topic in more detail. So be prepared for follow-up questions.

"Symmetric encryption is the process of encrypting data by creating a key which can then be used to decrypt it. In this process, a single key is used for the encryption and decryption of the data. Asymmetric encryption is similar but uses different keys for each transmission. Typically, technicians will use asymmetric encryption during the first transmission of data, followed by symmetric encryption for subsequent transmissions. Using the different types of encryption in this manner ensures that security of the data while expediting transmissions once the communication channel has been established."

Symmetric encryption is an encryption method where the same key is used to encrypt and decrypt a piece of data. asymmetric encryption is where 1 key is used for encryption and a different key is used for decryption.
