Adaface SQL Online Test is the most accurate way to shortlist SQL Developers
Reason #1
Tests for on-the-job skills
The SQL online assessment test helps recruiters and hiring managers identify qualified SQL experts from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves expensive engineering time by filtering out unqualified candidates. The Adaface SQL Online Test screens candidates for the typical skills recruiters look for in an SQL developer:
- Create a relational database from scratch
- Create, alter and delete tables from a database
- Insert, update and delete data from a table
- Retrieve data from a database using select queries
- Filter data using where clauses and logical operators
- Order and limit data retrieved from a table
- Use aggregate functions and group data to gain more meaningful insights from a database
- Relate tables together using database relationships
- Use SQL join queries to retrieve data from multiple tables in a single query
- Master complex SQL subqueries
- Apply SQL string functions
Reason #2
No trick questions
Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.
The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.
Why we started Adaface ->Reason #3
Non-googleable questions
We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.
These are just a small sample from our library of 10,000+ questions. The actual questions on this SQL Online Test will be non-googleable.

Reason #5
Designed for elimination, not selection
The most important thing while implementing the pre-employment SQL Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.
Reason #6
1 click candidate invites
Email invites: You can send candidates an email invite to the SQL Online Test from your dashboard by entering their email address.
Public link: You can create a public link for each test that you can share with candidates.
API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.
Reason #8
High completion rate
Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.
This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.
Reason #9
Advanced Proctoring
User authentication
Plagiarism detection
IP proctoring
Web proctoring
Webcam proctoring
Copy paste protection
The hiring managers felt that through the technical questions that they asked during the panel interviews, they were able to tell which candidates had better scores, and differentiated with those who did not score as well. They are highly satisfied with the quality of candidates shortlisted with the Adaface screening.

SQL Online Test FAQs
Can I evaluate relational database management systems like MySQL, PostgreSQL, MS SQL instead of SQL?
Yes. We provide focused tests that can help you assess database management systems instead of query language SQL. You can review our standalone MySQL test, PostgreSQL test and MS SQL test for in-depth details on what kind of questions are used to evaluate those skills.
Can I evaluate SQL and coding skills in the same test?
Yes. We support testing multiple skills in the same test. You can get a customized test where MCQ questions are used to evaluate SQL knowledge and coding questions are used to evaluate hands-on programming skills. We can also restrict the coding questions to be solved only using a particular programming language if you job description expects a specific language.
Can I evaluate SQL and NoSQL (like MongoDB) in the same test?
Yes. You can review our standard MongoDB test to get a sense of what questions are asked to evaluate MongoDB skills. In the final assessment you will have questions to evaluate SQL and MongoDB in the same test.
Can I evaluate other relevant skills like Python in the same test?
Yes. We support screening multiple skills in a single test. You can review our standard Python test to understand what type of questions we use to evaluate Python skills. Once you sign up for any plan, you can request a custom assessment that will be customized to your job description. The customized assessment will include questions for all the must-have skills required for your SQL role.
Can I combine multiple skills into one custom assessment?
Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.
Do you have any anti-cheating or proctoring features in place?
We have the following anti-cheating features in place:
- Non-googleable questions
- IP proctoring
- Web proctoring
- Webcam proctoring
- Plagiarism detection
- Secure browser
Read more about the proctoring features.
How do I interpret test scores?
The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.
What experience level can I use this test for?
Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.
Does every candidate get the same questions?
Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
I'm a candidate. Can I try a practice test?
No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.
What is the cost of using this test?
You can check out our pricing plans.
Can I get a free trial?
Yes, you can sign up for free and preview this test.
I just moved to a paid plan. How can I request a custom assessment?
