10 SAS interview questions and sample answers
To earn a job where you use SAS, you should be prepared to discuss your relevant knowledge and skills in an interview. In addition to basic questions about goals and work habits, interviewers ask candidates for SAS roles about their technical knowledge of SAS software and the skills they use to improve computing processes. Review these example SAS questions and answers to start preparing for how you'll answer questions during an interview:
1. What is the significance of the date January 1, 1960, in SAS?
This beginner-level question helps employers identify which candidates know the basics of the SAS system. Employers ask this question to determine if candidates understand database date values in general and in reference to SAS in particular. When answering this question, discuss the general meaning of the date and how it impacts SAS operations.
Example: "In SAS, all dates count backward or forward to midnight on January 1, 1960. It is the relative point in time that anchors all values in a database, simplifying calculations for statistical analysis. All dates after January 1, 1960, have positive values while all dates before January 1, 1960, have negative values."
2. How do you determine which functions to automate with a macro?
SAS programmers and developers create automated macros to help their employer consistently track common searches. SAS professionals should be able to take the initiative to program new macros to simplify their workflows. You can use your response to demonstrate your efficiency, observation and problem-solving skills.
Example: "Any time I notice a similar report being requested or anticipate the need to monitor a particular metric, I create a macro to ensure I don't have to repeat work."
3. What resources would you use to find the answer to a SAS programming question?
SAS has almost unlimited functions due to it many versatile functions. Even experienced SAS experts may discover problems that they don't have an immediate solution to. Your answer to this question can show that you're willing to learn and able to use your resources in the workplace to develop SAS solutions.
Example: "If I have a question, I start by reviewing the SAS handbook and searching SAS forums before reporting to my senior colleagues about the problem."
4. How do you maintain code quality standards in your work?
SAS roles require you to understand and write code, and employers want to ensure that you can complete a high standard of work. Interviewers look for candidates who know the basics of proper coding syntax. Use this question to explain your plan for upholding coding conventions when executing operations in SAS,
Example: "I make sure my code meets standard conventions by always reviewing my work for common issues like misplaced spacing and punctuation."
5. What strategies do you use to improve your SAS skills?
SAS roles require an extensive amount or problem-solving and troubleshooting, so employers seek out job applicants who show growth potential. When describing your ability to grow your SAS capabilities, focus on how you've learned new SAS features to solve problems in other professional environments.
Example: "I take regular continuing education courses to ensure my SAS knowledge is up-to-date and find new ways to apply my existing skills."
6. How would you integrate multiple data sets in different formats?
SAS experts should be able to manipulate data reports and synthesize various types of information into a single data set. When responding to this question, you can give examples of how you visually represent different variables in SAS and explain your process for re-categorizing information in a database.
Example: "In past roles, I started by translating both data sets to a neutral form of organization, using common data fields to connect the two formats. Then, I'm able to turn the combined data set into charts and other visualizations as necessary."
7. How does SAS process missing data values?
Interviewers ask this question to learn about your understanding of how SAS processes information, ensuring that you can properly interpret data reports. In your reply, discuss how SAS responds to unknown variables and explain the impact of missing data on your statistical analysis.
Example: "SAS automatically represents missing values with a period in the database. When processing data, you can also create provisions to stop the report if a field is empty."
8. How would you learn about the features of a new SAS update?
SAS is an evolving software suite that releases regular updates. Employers look for candidates who can adapt to the changes and new features of each version of SAS. Discuss how you stay informed about SAS updates and practice those changes in your work.
Example: "I always review the official SAS update statement to learn about new features, then practice using those features in a real database to get comfortable."
9. Describe each of the SAS data categories
Knowing the main types of data that SAS uses is essential for running useful data modeling reports and writing code that correctly accesses database information. List each category and talk about how they sort information in SAS.
Example: "The two data types in SAS are fixed character values and real numbers. They generate numerical statistics based on whatever measurements the clients track."
10. What would you do if a SAS macro suddenly stopped working?
Employers may ask you to describe what you would do in certain situations to assess your problem-solving process. This question reviews your knowledge of SAS macros and your ability to troubleshoot issues. Provide an overview of the steps you would take to diagnose and fix a broken macro.
Example: "If a macro stopped working, I'd restart the session then review the source code to look for where the execution failed. I'd also make sure that all values fit the requirements of the macro."
