About This Test

How long will the assessment be?

The assessment will have 20 multiple choice questions (MCQ) and will take ~45 minutes. We can also combine multiple skills into one assessment.

How is the assessment customized?

We use multiple factors to customize the assessment to your role:

  • Seniority level of the role: The seniority level of the role decides which concepts are more important to test. Simply increasing the difficulty level of the test does not necessarily make it more suited for a more senior role.
  • Combining multiple skills into one test: If you're looking for a Full Stack Engineer who knows ReactJS on the frontend, and NodeJS on the backend and can work with CSS, we'll set up an assessment with questions on JavaScript, NodeJS, ReactJS, HTML and CSS.
  • Ideal candidate persona: We try and understand what is the ideal candidate that you are looking for. For e.g. For a tech role- is there a focus on algorithms? That decides what type of coding challenges we use.

Score Distribution

You should expect ~20% of the candidates to do well on Adaface assessments.

The score distribution for our assessments follow the normal curve. This is a good sign- standardized tests like SAT and GRE follow the normal distribution (bell curve).

Status quo assessments typically have the exact opposite of the bell curve (too many candidates getting close to 0, too many candidates getting close to 100 and too few candidates in the middle). This is typically because they focus on theoretical questions or trick questions, which are very binary in nature- either you know the trick/ theory or you don’t.

FAQs

What is a custom assessment?

Every role is different and requires a custom assessment to identify top candidates efficiently. Adaface subject matter experts understand your job description/ role requirements and pick the most relevant questions from our library of 10000+ questions to create a technical assessment that helps you find the qualified candidates in your candidate pipeline quickly. All custom assessments are set up based on the job description, role requirements, must-have skills, experience level and salary range within a maximum of 48 hours and you will get an email notification once it goes live.

Check out a sample assessment here (no credit card required).

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.

How is Adaface different from other assessment tools?

We believe that status quo tech assessment platforms are not a fair way for companies to evaluate engineers because they focus on trick questions/ puzzles/ niche algorithms. We started Adaface to help companies find great engineers by assessing on-the-job skills required for a role. Read more about why we started Adaface.

Here's what's different with Adaface:

  1. High quality non-googleable questions that test for on-the-job skills as opposed to theoretical knowledge.
  2. A friendly conversational assessment with a chatbot, instead of sending a "test" to a candidate. This translates to a higher completion rate. Adaface assessments (86% candidate completion rate), as opposed to traditional tests (40-50% candidate completion rate)
  3. Customized assessments for 700+ skills at different experience levels.
Do you have any anti-cheating features in place?

We have the following anti-cheating features in place:

  1. Web proctoring
  2. Webcam proctoring
  3. Plagairism detection
  4. Non-googleable questions
  5. Secure browser

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. As in an assessment is optimizing 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 60%, 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 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.

What is the cost for using the PostgreSQL Online?

About The PostgreSQL Job Roles:

PostgreSQL, also known as Postgres, is a free and open-source relational database management system emphasizing extensibility and SQL compliance. PostgreSQL requires very minimum maintained efforts because of its stability.  Therefore, if you develop applications based on PostgreSQL, the total cost of ownership is low in comparison with other database management systems. Many companies have built products and solutions using PostgreSQL. Some featured companies are Apple, Fujitsu, Red Hat, Cisco, Juniper Network, etc.

Millions of developers and companies rely on PostgreSQL as their transactional data store of choice to drive application health and decision-making. With a high demand for PostgreSQL database admins, lots of software engineers simply add it to their resume/ CV, but they fall short when more advanced tasks that require specific database and software development experience need to be completed. The PostgreSQL online test is designed to help you find the most qualified PostgreSQL experts.

Typical responsibilities of a PostgreSQL Database Admin might involve: 

  • Implement and maintain database code in the form of stored procedures, scripts, queries, views, triggers, etc.
  • Primary on day to day schema changes and database maintenance
  • Work with front end developers to define simple yet powerful APIs.
  • Work with DBAs and data analysts to ensure database code is accurately documented.
  • Assist in Defining and implementing maintenance plan for the database
    systems

The test is designed to filter out candidates for roles like:

  • Database Administrator
  • PostgreSQL Developer
  • System Administrator 
  • DevOps Engineer
