Coding & DSA Assessment (DSA Coding Online Assessment — Mock) — Free Online Mock Test
A data-structures, algorithms and CS-fundamentals assessment — the screen used by product and unicorn companies (Google, Amazon, Microsoft, Meta, Flipkart, Swiggy, Paytm, PhonePe). Their real online assessments are 2–4 live coding problems on HackerRank / Codility / CodeSignal (Amazon adds a Work-Simulation and a Leadership-Principles Work-Styles module); this mock drills the underlying DS/algorithms, complexity and output-prediction knowledge in MCQ form. No negative marking. · Official language: English & Hindi.

Coding & DSA Assessment key facts & eligibility
| Conducting body | Format used across product-company hiring (this is an original practice board, not an official test of any one employer) |
|---|---|
| Official website | wrexaedge.com ↗ |
| Mode | A timed, test-case-driven coding assessment that mirrors the online-assessment round product companies use — you write full programs judged on hidden test cases. |
| Frequency | Practise on demand — the online-assessment round itself is scheduled by each employer’s hiring cycle. |
| Scoring & marking | A typical product-company coding round gives one to three algorithmic problems in a fixed window (often around 60–90 minutes), each graded automatically on hidden test cases across arrays and strings, hashing, two pointers and sliding window, sorting and searching, recursion, trees and graphs, and dynamic programming. Partial credit usually comes from passing a subset of test cases; there is no negative marking, and correctness plus time and space efficiency decide the score. |
| Score validity | Each employer’s online-assessment result applies within its own hiring cycle. |
| Language | English, with your choice of common programming language (C++, Java, Python and others). |
Who is eligible for Coding & DSA Assessment?
The real online assessment’s eligibility is set by the specific employer and role; there is no bar to practising the format here. Most product-company software roles target students and graduates of computer-science and allied degrees, but many run skill-first drives open to any background.
