RPA Interview Questions and Answers

1. What is Robotic Process Automation (RPA)?

   • Answer: Robotic Process Automation (RPA) is a technology that uses software robots to automate repetitive, rule-based business processes. These robots mimic human actions interacting with applications and systems, automating tasks like data entry, processing transactions, and managing emails.

2. What are the benefits of implementing RPA?
