Recruiter gave me instructions the following
• 90 minutes on a shared screen, coding from scratch in a browser “fiddle” (think .NET Fiddle) without IntelliSense, autocompletion, code snippets, or project scaffolding.
• Talk thru approach, then implement, run, test, and iterate solo. They’re assessing hands on ability, correctness, clarity, and resilience without IDE crutches
• Syntax from memory: classes, methods, generics, LINQ, async/await, exceptions, collections, null handling.
• Algorithms & data structures: arrays/strings, hash maps/sets, stacks/queues, sorting, two pointers, recursion/DFS/BFS, intervals.
• Clean coding under pressure: small, named methods; no magic numbers; tests or assertions.
