Bitwise: Coding Interviews
Get Better, 10 Minutes a Day
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Get better at coding interviews without turning preparation into a second job.
Bitwise is built around two ideas: consistent practice should fit into a busy day,
and the best way to learn a solution is to understand how it is built.
In short sessions, you construct interview solutions one decision at a time. Each
step asks you to choose what the solution should do next, then explains why that
choice works and how it moves the algorithm forward.
You do not just reveal an answer. You practice the thinking that produces it.
Ten focused minutes a day can help you recognize patterns faster, reason through
tradeoffs more clearly, and approach coding tests with more confidence—without
hours of grinding through an endless problem list.
Work through interactive Code Builder puzzles inspired by the algorithms and data
structures that appear in technical interviews. Instead of staring at a blank
editor or passively reading a solution, you assemble the key steps, test your
reasoning, and see why each choice works.
BUILD SOLUTIONS ONE DECISION AT A TIME
Turn a problem into a working approach through a sequence of focused decisions.
See the solution take shape as you choose data structures, handle edge cases, and
connect each step to the one before it.
LEARN THE THINKING, NOT JUST THE ANSWER
Get clear feedback on why each decision works. Check the finished solution against
examples and tests, then reason through its time and space complexity. Hints are
there when you need them.
MAKE PROGRESS IN MINUTES
Complete focused practice in sessions designed to fit around work, school, and
life. Return for quick reviews that reinforce the pattern before you forget it.
PRACTICE IN YOUR LANGUAGE
Explore solutions in Python, JavaScript, TypeScript, Java, C#, Swift, C, C++, and
Go.
RETAIN WHAT YOU LEARN
Completed puzzles return for review on a spaced schedule. Track the skills you
have practiced, revisit bookmarked problems, and build a routine that fits around
your day.
START FREE
Three complete starter puzzles are included at no charge. Bitwise Membership unlocks the
