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 Cryptography Test?

The Cryptography 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 digital signatures for secure authentication
  • Applying cryptography algorithms like RSA for secure data transmission
  • Utilizing hashing techniques for data integrity and password storage
  • Performing encoding and decoding operations for secure data exchange
  • Understanding the fundamentals of cyber security and its importance
  • Applying encryption techniques to protect sensitive information
  • Analyzing cryptographic protocols and identifying vulnerabilities
  • Implementing secure key management practices
  • Understanding the principles of public key infrastructure (PKI)
  • Integrating secure authentication mechanisms into applications

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 Cryptography Test?

Digital Signatures: Digital signatures are a cryptographic mechanism used to verify the authenticity and integrity of digital information. By using public key cryptography, a digital signature ensures that a document or message has not been tampered with and originated from a specific sender. This skill is measured in the test to assess a candidate's understanding of secure communication protocols and their ability to verify the integrity of digital data.

Cryptography Algorithms (like RSA): Cryptography algorithms, such as RSA (Rivest-Shamir-Adleman), are fundamental building blocks for secure communication and data protection. RSA is a widely used encryption algorithm that relies on the mathematical properties of large prime numbers. Testing a candidate's knowledge of cryptography algorithms in this assessment helps evaluate their proficiency in designing secure systems and protecting sensitive data.

Hashing Techniques: Hashing techniques are essential for ensuring data integrity and quick data retrieval. Hash functions convert input data into a fixed-size hash value, which can be used to uniquely identify the original data. Measuring a candidate's knowledge of hashing techniques in this test allows recruiters to assess their understanding of data integrity check mechanisms and their ability to efficiently retrieve data in a secure manner.

Encoding and Decoding: Encoding and decoding involve transforming data from one form to another, often necessary for secure transmission or storage. Encoded data is typically unreadable without the decoding process and can involve various techniques like base64 encoding. Evaluating a candidate's understanding of encoding and decoding techniques in this assessment helps gauge their ability to safeguard data during transit and ensure compatibility between systems.

Cyber Security Fundamentals: Cybersecurity fundamentals cover foundational knowledge about security protocols, threat management, risk assessment, and defense mechanisms. By including this skill in the assessment, recruiters can gauge a candidate's knowledge of security best practices and their ability to recognize and mitigate common cyber threats, making them valuable assets in protecting a company's digital assets and infrastructure.

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.
