Prep for quant developer interviews in a few minutes a day. qdev blitz turns the questions that come up in C++ and Python interviews at trading firms into short multiple-choice lessons. Read a snippet, then predict its output, find the bug, spot the race condition, or reason about complexity and cache behavior. Every answer comes with a short explanation of the idea behind it. TWO TRACKS • C++: core language, memory and object lifetime, templates, the STL, concurrency and memory ordering, operating systems, and low-latency performance. • Python: the data model, data structures and their costs, functions and OOP, the GIL and concurrency, CPython internals, NumPy and pandas, and operating systems. Study one or both, and switch between them any time. LEARN IN A WAY THAT STICKS • Lessons of 8–10 questions that ramp up in difficulty • Missed questions come back until you get them right, then return in spaced reviews • Take the placement test to start at your level, or jump ahead with a checkpoint • Streaks, a daily XP goal and an optional reminder keep you consistent BLITZ MODE Answer against the clock for bonus XP: 30 seconds for concept questions, 60 for code. PREMIUM The full path is free, limited by hearts. Premium adds unlimited hearts, blitz mode, a searchable question bank, jumping straight to any section without a checkpoint, and full stats: mastery by section, accuracy by question type and 30 days of XP. Start with a 7-day free trial. Premium is an auto-renewing monthly subscription. After the free trial, payment is charged to your Apple Account, and the subscription renews each month unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
