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

The MS SQL 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:

Writing complex SQL queries
Designing efficient databases
Applying normalization techniques
Optimizing database performance
Using indexes effectively
Utilizing various types of joins
Creating and working with subqueries
Understanding and working with views
Implementing and managing stored procedures
Working with triggers for automated actions

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 MS SQL Online Test?

SQL queries: SQL queries are statements used to retrieve data from a database. They are crucial for extracting specific information and performing operations on the database, such as filtering, sorting, and aggregating data. Measuring this skill in the test ensures candidates have a strong understanding of SQL syntax and the ability to write efficient queries.

Database design: Database design involves creating the structure and organization of a database, including tables, relationships, and constraints. It is essential to assess this skill to determine if candidates can design efficient and scalable databases that meet business requirements.

Normalization: Normalization is the process of organizing data in a database to eliminate redundancy and improve data integrity. Evaluating this skill helps identify candidates who can design databases that are properly normalized, reducing data duplication and improving data consistency.

Indexes: Indexes are database structures that improve query performance by enabling faster data retrieval. Measuring this skill ensures candidates understand the importance of choosing and creating appropriate indexes to optimize query execution.

Joins: Joins are used to combine data from multiple tables based on related columns. This skill is crucial for candidates to demonstrate proficiency in writing join statements and efficiently retrieving data from multiple tables.

Subqueries: Subqueries are nested queries within a SQL statement. Assessing this skill helps identify candidates who can write complex queries and leverage subqueries to retrieve data from multiple levels and achieve desired results.

Views: Views are virtual tables created from the result of a query. Measuring this skill ensures candidates can create, modify, and use views effectively to simplify complex queries, enhance data security, and improve query performance.

Stored procedures: Stored procedures are precompiled SQL code stored in a database, providing a way to execute complex operations. Evaluating this skill helps determine if candidates can design and write efficient stored procedures for implementing complex business logic in the database.

Triggers: Triggers are special types of stored procedures that are automatically executed in response to specific events, such as INSERT, UPDATE, or DELETE operations. This skill assessment helps identify candidates who can design and utilize triggers to enforce data integrity, implement validations, or automate certain database actions.

Transactions: Transactions are logical units of work that consist of multiple database operations, ensuring data consistency and reliability. Evaluating this skill helps determine if candidates understand the concept of transactions and can effectively manage them to maintain data integrity.

Performance tuning: Performance tuning involves optimizing the performance of a database by adjusting configurations, indexes, queries, and other factors. Assessing this skill helps identify candidates who can analyze and improve the performance of a database in terms of query speed, resource utilization, and overall efficiency.

Data manipulation: Data manipulation involves modifying the contents of a database using INSERT, UPDATE, DELETE, and similar operations. Measuring this skill ensures candidates can effectively manipulate data in a database, ensuring accurate and efficient data updates and modifications.

Data definition: Data definition involves defining the structure, organization, and attributes of data in a database using CREATE, ALTER, and DROP statements. Evaluating this skill helps determine if candidates can accurately define database objects, such as tables, columns, constraints, and indexes.

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.

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?
