How does RPA differ from Artificial Intelligence?<\/strong><\/li>\n<\/ol>\n\n\n\nRPA automates structured, rule-based tasks. It follows predefined steps. AI, on the other hand, deals with unstructured data, learns patterns, and makes decisions. RPA can be combined with AI to build more advanced intelligent automation, but alone, it does not learn or think.<\/p>\n\n\n\n
Note: <\/strong>Interview questions for RPA often focus on practical automation use cases, real-time problem solving, and knowledge of tools like UiPath.<\/p>\n\n\n\n<\/span>RE Framework UiPath Interview Questions<\/span><\/h2>\n\n\n\nHere are some advanced UiPath interview questions on the RE Framework to help you understand its components and applications.<\/p>\n\n\n\n
\n- What is the role of the Init state in REFramework?<\/strong><\/li>\n<\/ol>\n\n\n\n
The Init state is where the process begins. It reads the Config file, loads settings, initializes applications, and checks system availability. If initialization fails, the framework retries or ends gracefully.<\/p>\n\n\n\n
\n- How do you configure the Get Transaction Data state for queue items?<\/strong><\/li>\n<\/ol>\n\n\n\n
In this state, the next transaction item is fetched, usually from an Orchestrator Queue. The \u201cGet Transaction Item\u201d activity retrieves one item at a time. If no items are left, the state moves to the End Process. This setup allows high-volume data processing.<\/p>\n\n\n\n
\n- What is the difference between Business Exception and Application Exception?<\/strong><\/li>\n<\/ol>\n\n\n\n
A Business Exception happens when the data itself is invalid or does not meet business rules, like a missing invoice ID. An Application Exception occurs when a technical issue happens, such as a timeout or system crash. Business Exceptions skip the item, while Application Exceptions usually trigger retries.<\/p>\n\n\n\n
\n- How does the REFramework handle retries automatically?<\/strong><\/li>\n<\/ol>\n\n\n\n
Retries are managed at two levels. For failed transactions, Orchestrator retries can be set at the queue level. Inside the framework, the Set Transaction Status activity marks items and decides whether to retry based on exception type. This reduces manual error handling.<\/p>\n\n\n\n
<\/span>UiPath Orchestrator Interview Questions<\/span><\/h2>\n\n\n\nThese UiPath interview questions focus on Orchestrator and will help you prepare for managing, deploying, and monitoring automation processes effectively.<\/p>\n\n\n\n
\n- What are the different types of Robots in Orchestrator?<\/strong><\/li>\n<\/ol>\n\n\n\n
There are mainly two types: Attended and Unattended. <\/p>\n\n\n\n
Attended robots run with user input, often triggered by actions.<\/p>\n\n\n\n
Unattended robots run without human presence, in virtual environments, and can be scheduled. Development and Non-Production robots are also available for testing and building.<\/p>\n\n\n\n
\n- What is the difference between Standard Machine and Machine Template?<\/strong><\/li>\n<\/ol>\n\n\n\n
A Standard Machine is tied to one specific machine name. It\u2019s useful when the robot always runs on the same computer. A Machine Template is flexible and allows floating robots to run on multiple machines, often used in enterprise environments.<\/p>\n\n\n\n
\n- How do you schedule a process in Orchestrator?<\/strong><\/li>\n<\/ol>\n\n\n\n
In Orchestrator, go to the Triggers section. Choose the process, set start time, frequency, and target robots. For example, I can schedule a job to run daily at midnight. Orchestrator will then trigger the job automatically without manual intervention.<\/p>\n\n\n\n
\n- What are assets in Orchestrator and how are they used in automation?<\/strong><\/li>\n<\/ol>\n\n\n\n
Assets are shared values like credentials, URLs, or settings. They can be of type String, Boolean, Integer, or Credential. In workflows, I fetch them using the Get Asset or Get Credential activities. This allows central management of values without hardcoding them in processes.<\/p>\n\n\n\n
<\/span>UiPath Coding Interview Questions<\/span><\/h2>\n\n\n\nHere are some practical interview questions on UiPath coding that test your workflow design.<\/p>\n\n\n\n
\n- How do you convert a string variable to integer in UiPath?<\/strong><\/li>\n<\/ol>\n\n\n\n
Use an Assign activity:<\/p>\n\n\n\n
intValue = Convert.ToInt32(stringVariable)<\/p>\n\n\n\n
Or:<\/p>\n\n\n\n
intValue = CInt(stringVariable)<\/p>\n\n\n\n
\n- What is the difference between For Each, For Each Row, and Parallel For Each?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n- For Each (collection):<\/strong><\/li>\n<\/ul>\n\n\n\n
For Each item In myList<\/p>\n\n\n\n
Log Message: item.ToString<\/p>\n\n\n\n
Next<\/p>\n\n\n\n
\n- For Each Row (DataTable):<\/strong><\/li>\n<\/ul>\n\n\n\n
For Each row In dataTable<\/p>\n\n\n\n
Log Message: row(“ColumnName”).ToString<\/p>\n\n\n\n
Next<\/p>\n\n\n\n
\n- Parallel For Each:<\/strong><\/li>\n<\/ul>\n\n\n\n
Parallel For Each item In myList<\/p>\n\n\n\n
Assign result = item * 2<\/p>\n\n\n\n
End Parallel<\/p>\n\n\n\n
\n- How do you pass data between workflows in UiPath?<\/strong><\/li>\n<\/ol>\n\n\n\n
Create Arguments:<\/p>\n\n\n\n
