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.

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 Erlang (Coding): Entry Level Algorithms Test?

Basic Erlang Syntax: Understanding Erlang syntax is foundational for writing effective code. Knowledge of basic syntax ensures that the code is readable and maintainable.

Data Types and Variables: Erlang has distinct data types and variable-handling rules. Mastery of these allows for efficient data processing and manipulation.

Pattern Matching: Pattern matching facilitates assigning values to variables based on a specific structure. It simplifies complex condition checks and is crucial for efficient code.

List Manipulation: Lists are a primary data structure in Erlang. Effective list manipulation is essential for managing collections of data.

Recursion: Recursion is a key technique for looping in Erlang. It is fundamental for processing lists and implementing algorithms.

Higher-Order Functions: Higher-order functions can take other functions as arguments or return them. This capability allows for more abstract and potentially reusable code structures.

Error Handling: Erlang's approach to error handling, through techniques like 'let it crash', makes systems robust and fault-tolerant. Understanding this is essential for building resilient applications.

Concurrency Basics: Erlang's concurrency model, based on lightweight processes, is one of its key strengths. Mastering this is vital for developing scalable applications.

Basic OTP Concepts: The Open Telecom Platform (OTP) provides a set of libraries and design principles. These are crucial for building fault-tolerant and scalable systems in Erlang.

File Input/Output: Reading from and writing to files is a common necessity. Proficiency in file I/O operations is essential for many practical applications.

String Manipulation: String operations are fundamental for handling text data. Efficient string manipulation skills are necessary for processing and transforming text.

Simple Algorithm Implementation: Implementing basic algorithms demonstrates problem-solving skills and coding proficiency. This is crucial for evaluating an entry-level developer's capabilities.

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.
