Top 15 SAS Interview Questions & Answers [2025 Edition]

Let’s dive into the questions you’re most likely to face—broken down for every experience level and mapped to the latest hiring trends.

1. What is the significance of the date Jan. 1, 1960, in SAS?
   Answer: All SAS dates are calculated relative to midnight January 1, 1960. Dates after have positive values, before have negative ones—this standardizes date calculations. (Fundamental for freshers!)
2. How do you determine which functions to automate with a macro in SAS?
   Answer: Automate repetitive or error-prone tasks using macros—this improves efficiency and reduces manual mistakes. Macros are best for tasks repeated across multiple steps or datasets.
3. Explain the difference between the DO WHILE and DO UNTIL loops in SAS.
   Answer: DO WHILE checks the loop condition before running; if false, the loop never runs. DO UNTIL checks after the loop runs, guaranteeing at least one iteration.
4. How do you validate the accuracy and reliability of your SAS programs?
   Answer: Use comprehensive testing, review SAS logs, apply PROC COMPARE, conduct peer reviews, and document results. Ensures data integrity and reduces bugs.
5. Describe a project where you used SAS to solve a business problem.
   Answer: Share a concise story: state the business problem, your data approach, SAS techniques used, and the measurable impact (e.g., predictive modeling that cut churn by 15%).
6. What is the difference between an Informat and a Format in SAS?
   Answer: Informat reads raw data and converts it into SAS values; Format controls how SAS values are displayed.
7. How do you handle missing values in SAS datasets?
   Answer: Treat missing data by imputing values, flagging for audit, or excluding based on context. Always report your approach for transparency.
8. What are common error types in SAS, and how do you troubleshoot them?
   Answer: Typical errors: syntax, data step, macro errors. Debug using SAS logs, debugging options (MPRINT, SYMBOLGEN), and incremental testing.
9. Explain how PROC SQL is used in SAS and give an example.
   Answer: PROC SQL allows SQL-style data querying inside SAS, streamlining data manipulation and joins. Example:
   PROC SQL; SELECT * FROM employees WHERE salary > 70000; QUIT;
10. What is PROC TEMPLATE and its use?
    Answer: PROC TEMPLATE customizes the appearance of SAS ODS output, allowing for professional, branded reports and dashboards.
11. Which SAS versions and modules (Base, Macro, SQL, SAS/CONNECT, GRID) have you worked with?
    Answer: Highlight recent experience, especially with parallel processing (SAS Grid) and modules relevant to the job description.
12. How do you handle global multicenter clinical trial data using SAS?
    Answer: Use modular templates, metadata-driven code, and adhere to compliance standards (SDTM, ADaM, SOPs) for regulatory consistency.
13. What are the benefits of choosing SAS over other data analytics tools?
    Answer: SAS offers robust enterprise-grade solutions, security, scalability, and excellent customer support. It handles massive datasets with advanced analytics features.
14. How do you debug SAS macro code?
    Answer: Use options like MPRINT, SYMBOLGEN, MLOGIC to trace macro execution paths and identify logic errors.
15. How do you stay updated with SAS advancements and improve your skills?
    Answer: Follow SAS’s updates, join online forums, attend webinars, and practice through real-world projects. Continuous learning is key!
