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 15,000+ questions. The actual questions on this SQLite Online Test will be non-googleable.

🧐 Question
Medium Multi Select JOIN GROUP BY Sql Join Data Analysis	Solve
Consider the following SQL table: How many rows does the following SQL query return?
Medium nth highest sales Nested queries User Defined Functions	Solve
Consider the following SQL table: Which of the following SQL commands will find the ‘nth highest Sales’ if it exists (returns null otherwise)?
Medium Select & IN Nested queries	Solve
Consider the following SQL table: Which of the following SQL queries would return the year when neither a football or cricket winner was chosen?
Medium Sorting Ubers Nested queries Join Comparison operators	Solve
Consider the following SQL table: What will be the first two tuples resulting from the following SQL command?
Hard With, AVG & SUM MAX() MIN() Aggregate functions	Solve
Consider the following SQL table: How many tuples does the following query return?
Hard Find the customer with the most spend 2 JOIN GROUP BY ORDER BY	Solve
Given details of customers, products, and sales, write an SQL query to find the customer with the highest spend. The customer with the highest spend is the one who has spent the most money on purchases. The query should return the full name of the customer and the total amount spent by the customer rounded off to the nearest integer. full_name is the concatenation of first_name and last_name separated by a space. Eg: first_name = 'Alice', last _name = 'Brown' => full_name = 'Alice Brown' You can assume that there will always be non-empty first_name and non-empty last_name entries for all customers in the table.

What topics are covered in the SQLite Online Test?

SQLite Basics: SQLite Basics involves understanding the fundamental concepts and features of the SQLite database management system. It includes learning about database creation, table creation, data insertion, and retrieval. This skill is measured in the test to assess the candidate's familiarity with the basic operations and commands of SQLite.

Data Types: Data Types refers to the different types of data that can be stored in SQLite, such as integers, text, and floating-point numbers. It is important to measure this skill as it determines the candidate's understanding of how data is stored and managed in the database.

Queries: Queries involve retrieving specific data from the SQLite database using SQL statements. This skill is important to measure as it assesses the candidate's ability to write efficient and accurate queries to retrieve and manipulate data.

Joins: Joins are used in SQL to combine rows from two or more tables based on related columns. This skill is essential in assessing the candidate's understanding of how to retrieve data from multiple tables using different types of joins, such as inner join, outer join, and cross join.

Indexing: Indexing is the process of creating indexes on tables to enhance the performance of database queries. This skill should be measured to evaluate the candidate's knowledge of creating, managing, and utilizing indexes effectively to optimize query execution speed.

Transactions: Transactions in SQLite ensure the integrity and consistency of the database by grouping multiple database operations into a single logical unit. Measuring this skill is important as it tests the candidate's understanding of how to perform atomic transactions, handle concurrent access, and maintain data consistency in a multi-user environment.

Views: Views in SQLite are virtual tables that are derived from the result of a query. This skill needs to be measured as it evaluates the candidate's ability to create, modify, and utilize views to simplify complex queries and improve security by restricting access to underlying data.

Triggers: Triggers in SQLite are special stored procedures that are automatically executed when certain events occur, such as data modification or database operations. This skill should be measured to assess the candidate's understanding of how to create, manage, and utilize triggers to enforce data constraints, implement business rules, and maintain data integrity.

Normalization: Normalization is a process of organizing data in a database to eliminate redundancy and ensure data integrity. Measuring this skill is important as it evaluates the candidate's understanding of normal forms, functional dependencies, and the ability to design and optimize database schemas by applying normalization techniques.

Constraints: Constraints in SQLite define rules and limitations on the data that can be inserted, updated, or deleted from a table. This skill should be measured to assess the candidate's knowledge of different types of constraints, such as unique, not null, primary key, foreign key, and how to enforce data integrity through constraint enforcement mechanisms.

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?
