Certification course
by Japneet Sachdeva
Course description:
This course is built for manual testers and QA engineers who need to develop real coding ability from the ground up. Starting with Java fundamentals and progressing through arrays, strings, and essential data structures, each topic is approached at three levels — brute force, better, and optimal.
The focus throughout is on pattern recognition: learning to identify and apply the Two-Pointer, Sliding Window, and other core algorithmic techniques that appear most frequently in SDET technical interviews. By the end, you will be able to visualize solutions clearly and implement them efficiently in Java.
