Screen candidates with the highest quality 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

Test candidates on core NoSQL Hiring Test topics

Column-Store system: The Column-Store system is a database management system that stores data in columns instead of rows. This structure allows for faster data retrieval and analysis, especially for large datasets, as it only reads the columns needed, minimizing disk I/O and improving query performance.

Document-Store Id store system: A Document-Store Id store system is a database management system that stores and retrieves data in a document-oriented format, where each document is identified by a unique document identifier (ID). This allows for flexible and scalable data storage, as data is stored in a schema-less manner, accommodating varying data structures and types within each document.

Key-value solutions: Key-value solutions are data storage and retrieval systems that use a simple key-value pair structure, where each piece of data is associated with a unique key. This approach enables rapid data access and retrieval, making it ideal for caching, session management, and other scenarios where quick look-up operations are required.

Graph-Based Solutions: Graph-based solutions are database management systems that use graph structures to represent and store data. Graphs consist of nodes (representing entities or objects) and edges (representing relationships between nodes). This approach enables efficient querying and analysis of complex relationships and interconnected data, making it suitable for social networks, recommendations, and network analysis.

Column-Store solutions: Column-Store solutions are database management systems that store data in a columnar format, rather than the traditional row format. This organization allows for higher compression rates and improved query performance, as only the necessary columns are read during query execution. Column-Store solutions are particularly beneficial for data analytics and reporting, where aggregated queries over large datasets are common.

Document Store IT Solutions: Document Store IT Solutions are database management systems that focus on storing and retrieving data in a flexible and self-describing format, such as JSON or XML. This allows for the storage of semi-structured and structured data, facilitating dynamic schema evolution and supporting rapid development and iteration cycles.

We evaluated several of their competitors and found Adaface to be the most compelling. Great library of questions that are designed to test for fit rather than memorization of algorithms.

Have questions about the NoSQL Hiring Test?

How does pricing work?

You can check out our pricing plans.

Can I customize the test?

Yes, absolutely. Custom assessments are set up within 48 hours 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. You can also customize a test by uploading your own questions.

Can I combine multiple skills into one test?

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.

What roles can I use the NoSQL Test for?

Here are few roles for which we recommend this test:

  • NoSQL DataBase Engineer
  • Hadoop and NoSQL Operations Engineer
  • NoSQL Database Administrator
  • NoSQL Platform Engineer
Can I see a sample test, or do you have a free trial?

Yes!

The free trial includes one sample technical test (Java/ JavaScript) and one sample aptitude test that you will find in your dashboard when you sign up. You can use it to review the quality of questions and the candidate experience of giving a test on Adaface.

You can preview any of the 500+ tests and see the sample questions to decide if it would be a good fit for your requirements.

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.

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.
