Jira Administrator (Migration/Scripting/Integration)

A browsable practice library of coding problems that can be filtered by pattern, data structure, difficulty and company, so you can drill exactly the weakness you found this week. Patterns include two pointers, sliding window, hash maps, stacks, backtracking and greedy algorithms, with company filters for Google, Meta, Microsoft, Amazon, Oracle and LinkedIn. Free to browse, with an in-browser editor and solutions.

A structured learning path through coding interview preparation that brings together data structures and algorithms fundamentals, recursion and the pattern-based approach to coding questions in one order. It totals 77 chapters and 1,054 lessons, with quizzes, flashcards and a certificate. Use it when you have plenty of material but no clear plan for what to study first.

A practical course on negotiating compensation in tech, from preparing and building a strategy to specific tactics, the full package beyond base salary, handling multiple offers and asking for a raise. It has tailored sections for fresh graduates and experienced engineers. It suits anyone with an offer coming, and anyone who has ever accepted the first number out of discomfort.

A paid, human review of your resume by experienced engineers and hiring managers from large technology companies, returned in three to five business days with line-by-line suggestions, proposed rewrites of bullet points and applicant tracking system advice. It suits engineers whose resume is already reasonably solid and who want detailed feedback from people who screen engineering resumes for a living before a job search.

A quick-revision companion to the DSA roadmap in nine chapters: complexity, arrays and hashing, linked lists, stacks and queues, recursion, sorting and searching, trees and heaps, graphs, coding patterns, dynamic programming and timed practice habits. Costs are stated for every structure and algorithm, in Python, Java, C++ or JavaScript editions. Use it after each roadmap stage and before a contest or coding round.

An eight-stage path from Big-O through arrays, hashing, recursion, trees, graphs, coding patterns and dynamic programming to timed, mixed practice, in Python, Java, C++ or JavaScript. It suits students and developers who can write code but freeze on problems with no obvious library call. By the end you can pick the right data structure, recognise common problem shapes and solve a medium problem in about 35 minutes with edge cases tested.
