About the test:
The Solid Principles Test uses scenario-based multiple choice questions to evaluate candidates on their understanding of the SOLID design principles for object-oriented software development. The test assesses candidates' proficiency in applying SOLID principles to write maintainable, extensible, and testable code, including topics such as single responsibility principle (SRP), open-closed principle (OCP), Liskov substitution principle (LSP), interface segregation principle (ISP), dependency inversion principle (DIP), and the SOLID design patterns.

The SOLID Principles Online test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves expensive engineering time by filtering out unqualified candidates.
SOLID is an acronym for the five important object-oriented design (OOD) principles that are intended to make software designs more reusable, maintainable, understandable, and flexible. SOLID principles are used in all object-oriented programming languages such as Java, C#, Python, etc.
The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for the role. Anti-cheating features enable you to be comfortable with conducting assessments online. The SOLID Principles test is ideal for helping recruiters identify which candidates have the technical skills to do well on the job.
Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.
The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.Why we started Adaface ->
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.
These are just a small sample from our library of 10,000+ questions. The actual questions on this SOLID Principles Test will be non-googleable.

With Adaface, we were able to optimise our initial screening process by upwards of 75%, freeing up precious time for both hiring managers and our talent acquisition team alike!

The most important thing while implementing the pre-employment SOLID Principles Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.
Email invites: You can send candidates an email invite to the SOLID Principles Test from your dashboard by entering their email address.
Public link: You can create a public link for each test that you can share with candidates.
API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.
Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.
This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

In Object-Oriented Programming, SOLID is an acronym for five important design principles intended to make software designs more reusable, scalable, and robust. Promoted as a subset of a set of principles by Robert C Martin, the SOLID principles are important for the creation of robust software that has low coupling, high cohesion, and strong encapsulation.
S – Single-Responsibility Principle
O – Open-Closed Principle
L – Liskov Substitution Principle
I – Interface Segregation Principle
D – Dependency Inversion Principle
As per the SRP, a class must have only one responsibility and should do only the task for which it has been designed.
Benefits of using SRP: Reduced coupling and understandable code
As per the OCP, software entities such as classes, functions, modules, etc, should be written in such a way that it must be easily extensible with new features without changing its existing code in use.
Benefits of using OCP: Codebase that is robust and reusable
LSP was defined by Barbara Liskov and says that objects in a program must be replaceable by instances of their subtypes without altering the correct functioning of that program.
Benefits of using LSP: Class hierarchies are easier to understand
As per LSP, a class should not force any client to implement an interface that is irrelevant to them. It is the first principle that is applicable to Interfaces instead of classes.
Benefits of using ISP: Decoupled system and easy refactoring of code
As per DIP, a particular class should not depend directly on another class, but rather on an abstraction of this class.
Benefits of using DIP: Reduced coupling
SOLID principles are applicable for all object-oriented programming languages such as Java, C#, Python, etc.
The hiring managers felt that through the technical questions that they asked during the panel interviews, they were able to tell which candidates had better scores, and differentiated with those who did not score as well. They are highly satisfied with the quality of candidates shortlisted with the Adaface screening.
Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.
We have the following anti-cheating features in place:

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.
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.
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.
