Windows Workflow Interview Questions
A few people have asked me what "hard core" WF questions to ask a job candidate.
For advanced topics, I like open-ended questions. Not all these questions have a right or wrong answer- but they should give you an idea of the candidates WF experience, and how they'd design and implement software with WF.
- Are there advantages to building workflows using only XAML? Are there disadvantages?
- What are the pros and cons of using an ExternalDataExchange service versus going directly to the WorkflowQueuingService?
- When are attached dependency properties useful in WF programming?
- What behavior does the default scheduling service provide?
- How can my code participate in a database transaction with a workflow instance?
- Why would I use a tracking service?
- Describe a scenario where the WF runtime will cancel an executing activity.
- Describe a scenario where I'd need to spawn an ActivityExecutionContext.
- Tell me why I'd use a compensation handler.
- Tell me about the following activities: Replicator, Parallel, and Policy.
A candidate who can run the table on these 10 questions knows their WF stuff.
