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.

Why you should use Pre-employment Redis Test?

The Redis 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:

  • Implementing basic data structures in Redis
  • Utilizing core Redis commands for data manipulation
  • Configuring Redis persistence mechanisms
  • Setting up master-slave replication in Redis
  • Implementing basic Redis clustering configurations
  • Managing Redis transactions and optimistic locking
  • Implementing publish/subscribe messaging patterns
  • Configuring basic Redis security measures
  • Optimizing Redis performance for common use cases
  • Writing simple Lua scripts for Redis operations

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 Redis Test?

Data Structures in Redis: Redis offers a variety of data structures such as strings, lists, sets, sorted sets, and hashes. Understanding these data structures is essential for leveraging Redis to solve complex problems efficiently. This skill ensures that the developer can make the most out of Redis's versatile storage options.

Redis Commands: Redis commands are the core of its interface, allowing operations like setting and getting values, managing data structures, and controlling the server. Knowledge of these commands is pivotal in effectively using Redis. Mastery of Redis commands ensures efficient handling of data manipulation and server management.

Redis Persistence: Redis offers different persistence mechanisms like RDB snapshots and AOF logs to ensure data durability and recovery. Understanding these mechanisms helps maintain data integrity across server restarts. This skill highlights the developer's ability to configure and manage data persistence strategies.

Redis Replication: Replication in Redis allows for data redundancy and high availability by copying data from a master node to replica nodes. This skill involves setting up and managing replication to ensure system reliability. Proficiency in replication is crucial for fault tolerance and load balancing.

Redis Clustering: Redis clustering enables horizontal scaling by partitioning data across multiple nodes. It helps in distributing the load and ensuring consistent performance even with large datasets. Knowing how to configure and manage clusters is key to maintaining scalable applications.

Redis Transactions: Transactions in Redis provide a way to execute a series of commands atomically. Understanding transactions ensures data consistency, especially in multi-step operations. This skill indicates a developer's ability to maintain data integrity using Redis's transactional capabilities.

Redis Pub/Sub: The Publish/Subscribe (Pub/Sub) paradigm in Redis is used for messaging between applications. It is crucial for real-time applications where instant notification is required. This skill demonstrates the ability to implement efficient messaging patterns using Redis.

Redis Security: Security in Redis involves measures like authentication, encryption, and access control. Proper security practices protect against unauthorized access and data breaches. This skill ensures that a developer can implement and maintain robust security configurations in Redis environments.

Redis Performance Tuning: Optimizing Redis performance involves tuning various parameters and configurations to ensure optimal speed and resource usage. This skill helps in making applications more efficient and responsive. Performance tuning is crucial for high-throughput and low-latency operations.

Redis Lua Scripting: Lua scripting in Redis allows the execution of complex operations atomically and efficiently. It provides a way to extend Redis's functionality beyond basic commands. Proficiency in Lua scripting enhances the ability to implement custom, optimized operations.

Redis Monitoring and Debugging: Monitoring and debugging in Redis involve tracking performance metrics and diagnosing issues using various tools and commands. This skill is essential for maintaining reliable and high-performing Redis instances. Effective monitoring and debugging ensure system stability and quick issue resolution.

Redis Use Cases: Understanding various Redis use cases, from caching to real-time analytics, provides insights into how best to apply Redis in different scenarios. This knowledge helps in designing solutions that leverage Redis's strengths. Familiarity with use cases illustrates the versatility and practical applications of Redis in real-world projects.

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?
