Why You Should Use This Test

The Scala 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 tests screen candidates for the typical skills hiring managers look for in a Scala developer:

  • Knowledge of object-oriented programming
  • Experience working on JVM
  • Knowledge of Statistical analysis
  • Experience working with Distributed File Storage systems (like HDFS)
  • Knowledge of SQL and relational database management system

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

About This Test

The Scala test will consist of ~15 MCQ, 1 coding challenge and 1 debugging challenge crafted by experts in the Scala programming language and will cover a broad spectrum of topics within Scala. Use this Scala Online Quiz to streamline your hiring process.

The Scala Online Test helps you screen candidates. Interview only candidates with proven hands-on technical expertise in Scala development and programming.

The idea behind this online Scala quiz is to help you assess on-the-job Scala concepts, Core Scala knowledge, coding and debugging skills with just one test.

Here is a list of topics (only for reference, actual topics and questions for your custom assessment will be chosen by our subject matter experts based on your job description/ ideal engineer persona).

Datatype Conditional expressions Functions OOPs
Constructors Method overloading this Inheritance
final File handling Exception handling String
Tuples String interpolation case classes singleton objects

The Scala online test is designed to test for Scala fundamentals and hands-on coding skills:

  • Scala fundamentals: These questions are designed to evaluate a candidate's knowledge and expertise of technical concepts in Scala like OOPs, datatype, conditional expressions, comments, functions, exception handling, constructors, method overloading etc.
  • Coding skills: These questions are designed to assess a candidate's programming ability and debugging skills in Scala. In addition, these also test for problem solving skills.

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- tandardized 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 what we do differently at Adaface here.

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 developer 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 developer 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 Java developer roles for any experience level (unless the role is primarily a leadership/ non-programming role, we do not recommend you a use any automated assessments in that case).

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 an engineer. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment.

What is the cost for using the Scala Online Test?

Please get in touch, we'll create a custom plan for you based on the number of assessments you need.

Can I get a free trial?

About The Role

Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala source code is intended to be compiled to Java bytecode, so that the resulting executable code runs on a Java virtual machine. Scala provides language interoperability with Java, so that libraries written in either language may be referenced directly in Scala or Java code. This gives Scala developers a major advantage over other developers because they can access the very diverse Java ecosystem.

Scala is mainly used in backend development in highly concurrent applications.

Typical responsibilities of a Scala Developer include:

  • Developing, enhancing, re-engineering & maintaining applications with Scala.
  • Working with business and OTHER  to define, estimate, and deliver functionality.
  • Implementing Projects based on functional specifications.
  • Integration with AWS/Hadoop/HDFS, Real-Time Systems, Data Warehouses, and Analytics solutions.

What Are Conversational Assessments

What Are Conversational Assessments

Conversational assessments are the most candidate friendly way to get insights into a candidate's on-the-job skills and suitability for a role, while providing for a delightful candidate experience. Candidates love conversational assessments because they are fast, intuitive and feel like an interview rather than a test.
