COURSE OVERVIEW

A focused, practice-first video course that teaches the algorithmic patterns most commonly asked in SDET and automation interviews. Each lesson walks through the brute-force idea, optimizations, code implementation, and interview-ready explanation templates so you can solve problems under time pressure and explain your trade-offs clearly.

LEARNING OUTCOMES

Master core competencies for SDET coding rounds:

• Core data structures: arrays, strings, lists, maps, sets

• Algorithmic patterns: two-pointers, sliding-window, fast-slow pointers

• Searching & sorting fundamentals and trade-offs

• Brute → Optimize workflow: transform naive ideas into O(n) / O(n log n) solutions

• String manipulation & palindrome techniques

• Hashing patterns for pairs and subarray problems

• Problem decomposition and interview answer structuring (intent, approach, complexity)

• Quick correctness & complexity checks for production-ready code

• Time-boxed practice routines (30/60/90 days)

TARGET AUDIENCE

• Manual testers preparing for automation/SDET coding rounds

• Entry/intermediate engineers needing targeted DSA practice for interviews

• Bootcampers and students preparing for technical interviews

• Professionals seeking quick, prioritized practice to pass coding screens

PREREQUISITES

• Any programming language syntax understanding

• Familiarity with a language (Java recommended but any language is fine)

• A laptop with a code editor and ability to run simple scripts

COURSE MODULES (mapped to lesson videos)

Module 1: FOUNDATIONS (Videos 1–3)
