Technical screening questions
Ask for one example per question and listen for specifics.
- How do you onboard a new data source? A good answer: Forwarder, inputs, sourcetype and parsing.
- How do you write an efficient search? A good answer: Limit time and index first, then transform.
- What is the difference between a search head and an indexer? A good answer: Query layer versus storage and indexing.
- How do you reduce license usage? A good answer: Filtering, routing and data review.
- Describe a dashboard or alert you built. A good answer: Use case and result.
Quick screening questions
Use these when you have only a few minutes.

Run the call well
Ask for the last project first, then dig into the second or third question. Take notes on versions, team size and outcomes, and record them with the submission so the vendor’s later technical interview does not surprise you.
Frequently asked questions
How long should a Splunk engineer screening call take?
Fifteen to twenty minutes is enough to cover the project, three technical questions and availability, rate and work authorization.
Do recruiters need to know the technology?
Working vocabulary is enough. Use the sourcing guide for the role and listen for specifics instead of judging technical depth yourself.
