✦ 1. Executive System Overview & Purpose

SkillAssessment Tech Testing is an in-browser coding test, pre-employment technical screening, and developer competency assessment platform. Built for tech recruiters, engineering hiring managers, and software bootcamps, it evaluates software developer candidates with automated code execution.

Featuring an in-browser code editor supporting 20+ programming languages, automated test case grading against public and hidden unit tests, candidate anti-cheat webcam proctoring, and comprehensive competency scorecard analytics, SkillAssessment filters top-tier software engineers efficiently.

⚡ Candidate In-Browser Coding Terminal Features

✅ In-Browser Code IDE with 20+ Supported Languages

↳ Code in PHP, JavaScript, Python, Java, C++, Go, Rust, Ruby, SQL, C#, and Swift

↳ Monaco Editor Integration (Same Engine as VS Code) with Auto-Complete and Syntax Highlighting

↳ 1-Click "Run Code" Executing Candidate Solution Inside Isolated Secure Docker Containers

✅ Automated Unit Test Verification (Public & Hidden Tests)

↳ Run Code Against Sample Test Cases to Verify Logic and Corner Cases

↳ Final Evaluation Tests Against Strict Hidden Test Cases to Prevent Hardcoded Answers

↳ Code Execution Time (ms) and Memory Consumption (MB) Benchmarking

✅ Anti-Cheat Proctoring & Integrity Safeguards

↳ Copy-Paste Prevention: Disables Pasting External Code into Editor

↳ Candidate Code Playback (Watch Keystroke-by-Keystroke Video of How Candidate Wrote Code)

⚡ Recruiter Assessment Studio & Grading Features

✅ Coding Challenge Library & Custom Problem Builder

↳ Pre-Built Challenge Library (Data Structures, Algorithms, REST APIs, SQL Queries, Bug Fixing)

↳ Custom Problem Builder: Write Problem Statement, Starter Boilerplate, and Unit Tests

↳ Candidate Comparative Benchmarks (Compares Candidate Score to Global Developer Percentiles)

✦ 2. Operational Workflows

⚡ Admin Workflow

▸ Create technical screening test by selecting coding challenges matching job requisition skills

▸ Send unique test invitation link to candidate with 48-hour completion deadline

▸ Candidate takes test in browser; system executes code inside secure sandboxed Docker containers

▸ System grades solution automatically against unit tests and generates detailed candidate scorecard

▸ Hiring manager reviews code quality, algorithmic complexity, and advances top candidates

⚡ User Workflow

▸ Software candidate receives email invitation for technical assessment and opens link

▸ Selects preferred programming language and reads problem algorithmic requirements

▸ Writes solution in Monaco code editor; tests against sample test cases using "Run Code"

▸ Refines code to optimize time complexity; submits completed solution before timer expires

▸ System confirms submission; recruiter receives instant notification with scored code analysis
