Mettl Platform Demo: How to Navigate Skill Assessments and Solve the Problem
In this comprehensive guide, we explore the Mettl platform, a widely used skill assessment and proctoring tool favoured by companies for conducting placement drives. Whether you are preparing for a technical interview or a college placement test, this video will walk you through the platform's interface and a practical coding challenge.
What you will learn:
• Platform Overview: Understand how to access the test via test.mettl.com using a specific test code and how to navigate the guidelines, such as internet requirements and the "no-refresh" rule.
• System Compatibility: Learn about the initial system checks and how to provide your credentials to begin the assessment.
• The Coding Interface: Discover the layout of the platform, which includes a question section with examples on the left and a coding editor on the right that supports multiple languages like C, C++, Java, and Python.
• Working with Read-Only Code: We explain how to handle pre-defined function signatures and parameters in read-only regions where you only need to write the core logic without a main function.
• Solving the Coding Challenge: Follow a step-by-step solution to the "Non-repeated Digit Count" problem. We demonstrate how to use a frequency array to track digit occurrences and return the count of unique digits.
• Testing & Submission: Learn how to use the "Compile and Test" feature, provide custom inputs for debugging, and finally submit your code once all test cases pass.
By the end of this video, you will be familiar with the Mettl interface and the logic required to solve digit-based frequency problems in C
