Concurrency & Parallel Processing (Senior)
A 450-question senior-level bank, two-thirds Advanced or Expert, served as 40-question, 60-minute mocks: concurrency models, synchronization primitives, races and memory models, deadlock and liveness, lock-free programming, async I/O, multiprocessing and worker pools, parallel algorithms, language concurrency models (Go, Java, Python, Node.js, Rust), and concurrent design patterns. Language-agnostic where possible, verified by running Python and Node.js, and every option explains its reasoning.

What score do you need to pass it?
Results are reported from 0 to 100, and 70 is the passing score used in these mocks. Harder questions carry more weight.
What does the Concurrency & Parallel Processing (Senior) cover?
4 domains: Foundations (20%), Correctness (30%), Parallel and Asynchronous Processing (30%) and Languages and Design (20%).
How can I practise for it?
Start with the free 15-question diagnostic to find your weak spots, drill any skill with an explanation after every answer, retry your mistakes with spaced review, then sit timed full mocks.
How is my readiness score worked out?
It weighs your recent answers on each skill by difficulty, combines the skills by their exam weight into a predicted score, and reports your chance of reaching the pass mark. How scoring works
