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.

How we design questions

These are just a small sample from our library of 10,000+ questions. The actual questions on this T SQL Online Test will be non-googleable.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment T 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.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the T 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.

About the T SQL Assessment Test

Why you should use Pre-employment T SQL Online Test?

The T SQL Online Test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

  • T-SQL proficiency
  • Database design and normalization
  • SQL queries optimization
  • Indexing strategies
  • Data manipulation using T-SQL
  • Working with stored procedures
  • Understanding triggers and their applications
  • Creating and managing database views
  • Knowledge of transactions and ACID properties
  • Performance tuning and optimization

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the T SQL Online Test?

  • T-SQL

    T-SQL, or Transact-SQL, is a programming language used for managing relational databases. It allows users to retrieve and manipulate data stored in a Microsoft SQL Server. This skill is essential to assess as it forms the foundation of SQL query execution and database management.

  • Database Design

    Database design involves creating a structured framework for organizing data in a database system. It includes defining tables, establishing relationships, and ensuring data integrity. Measuring this skill is important as it assesses the candidate's ability to design efficient and scalable databases.

  • SQL Queries

    SQL queries are statements used to retrieve specific data from a database. They enable users to filter, sort, and combine data based on specific criteria. Assessing this skill helps evaluate the candidate's proficiency in constructing complex queries to extract relevant information from a database.

  • Indexes

    Indexes are database structures that improve query performance by allowing faster data retrieval. They help locate data quickly based on specified columns. Measuring this skill is crucial as it determines the candidate's understanding of optimizing database performance through index creation and usage.

  • Data Manipulation

    Data manipulation involves modifying data in a database, such as inserting, updating, and deleting records. It requires knowledge of SQL statements and database operations. Evaluating this skill helps gauge the candidate's ability to accurately manipulate data while maintaining data integrity.

  • Stored Procedures

    Stored procedures are pre-compiled database programs that can be executed repeatedly. They enhance database performance, encapsulate complex logic, and promote code reusability. This skill is important to measure as it reflects the candidate's proficiency in creating efficient and reliable procedures for data manipulation and retrieval.

  • Triggers

    Triggers are database objects that automatically execute predefined actions when a specific event occurs. They allow users to enforce data integrity and implement business rules. Assessing this skill helps evaluate the candidate's understanding of trigger creation and their ability to design effective mechanisms for enforcing data consistency.

  • Views

    Views are virtual tables created from queries that simplify data retrieval by providing a logical representation of data. They enable users to extract relevant information without directly accessing the underlying tables. Measuring this skill is crucial as it demonstrates the candidate's ability to create efficient and reusable views to simplify data access.

  • Normalization

    Normalization is the process of organizing data in a logical and efficient manner by reducing redundancy and dependency. It involves breaking down data into multiple tables and establishing relationships between them. Assessing this skill is important as it evaluates the candidate's understanding of database normalization principles and their ability to design well-structured database schemas.

  • Transactions

    Transactions ensure the integrity and consistency of data in a database by grouping multiple database operations into a single atomic unit. They guarantee that all operations within a transaction are executed successfully or rolled back if an error occurs. Measuring this skill is crucial as it demonstrates the candidate's understanding of data concurrency, consistency, and recovery.

T SQL Hiring Test FAQs

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. Here's a quick guide on how you can request a custom test.

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
  • Screen proctoring
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser
  • Copy paste protection

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.
