Why You Should Use This Test

The ETL Online Test helps recruiters and hiring managers to 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.

The Adaface ETL test screens candidates for the typical skills recruiters look for in a ETL developer:

  • Ability to determine data storage needs.
  • Expertise with designing, developing, automating, and supporting applications to extract, transform, and load data from different sources.
  • Ability to understand the logical and physical data flow models for ETL applications.
  • Expertise with troubleshooting and solving complex technical problems with ETL applications.

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 ETL test is ideal for helping recruiters identify which candidates have the technical skills to do well on the job.

About This Test

The ETL test will consist of ~25 MCQs and scenario-based challenges crafted by experts in the field of ETL and will cover a broad spectrum of topics within ETL. Use this ETL Online Quiz to streamline your hiring process.

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.

About The Role

The term ETL stands for Extract, Transform, and Load. It is a process by which data is extracted and shifted from various sources into a data warehouse.

E-EXTRACT

Data is extracted from the source system into the staging area. These sources can be text files, SQL servers, spreadsheets, or vendor data.

T-TRANSFORM

The data extracted from the previous process has to be cleansed, mapped, and transformed. This happens through the many validations that are set up for filtering and cleaning of data. 

L-LOAD

In this stage, data is loaded into the target warehouse database. 

An ETL developer is an IT specialist who designs data storage and data warehousing systems.

Typical ETL developer responsibilities include:

  1. Designing, developing, and maintaining the data warehousing system to desired company specifications.
  2. Ensuring the data quality of the extracted data.
  3. Create an enhanced data solution for the seamless delivery of data.
  4. Troubleshooting issues for optimized data flow.
