Why you should use Pre-employment Golang (Coding): Entry Level Algorithms Test?

The Golang (Coding): Entry Level Algorithms Test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

Writing basic Go syntax
Understanding Go data types
Utilizing control structures like loops and conditionals
Implementing functions in Go
Manipulating arrays and slices
Using maps for key-value storage
Handling errors and exceptions
Creating and using structs
Implementing interfaces in Go
Writing basic concurrent programs with goroutines

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 Golang (Coding): Entry Level Algorithms Test?

Basic Syntax: Understanding basic syntax in Golang is essential as it forms the foundation of the language. This includes learning how to write and structure code, which is necessary for writing any program in Go.

Data Types: Data types define the kind of data variables can hold, such as integers, strings, and booleans. Knowledge of data types is crucial for effective memory management and data manipulation.

Control Structures: Control structures such as loops and conditionals enable developers to dictate the flow of execution in a program. These constructs are fundamental for implementing logic in code.

Functions: Functions encapsulate code into reusable blocks, enhancing code readability and maintainability. They play a significant role in modular programming and reducing redundancy.

Arrays and Slices: Arrays and slices are essential for storing sequences of elements. They are fundamental to handling collections of data in a structured way, offering both fixed and dynamic storage solutions.

Maps: Maps provide a way to store key-value pairs, enabling efficient data retrieval. They are pivotal in scenarios requiring fast lookups and data association.

Concurrency: Concurrency involves managing multiple tasks simultaneously, leveraging Go's goroutines and channels. Proficiency in this area is important for building efficient and high-performance applications.

Error Handling: Error handling ensures robustness by managing and responding to runtime anomalies. Effective error handling is critical for building reliable and fault-tolerant programs.

Interfaces: Interfaces define methods that types must implement, promoting polymorphism and code flexibility. They allow different types to be treated uniformly based on shared behavior.

Structs: Structs allow the grouping of data into single entities, facilitating complex data structures. Mastery of structs is vital for modeling real-world entities in Go applications.

Read more about the proctoring features.

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.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.
