Coding interview practice, one technique at a time.

How to use this section

1. 1In the beginning, learn one category at a time.
2. 2Hold off on random problems until you are comfortable with Tier I · Fundamentals.
3. 3You do not have to finish a category before moving on, but do at least half of it.
4. 4Once you have solved a problem, read how other people solved it in the Solutions tab.
5. 5Studying DSA takes months, sometimes years. Set a schedule you will stick to: 10-15 hours a week for long-term learning, 30-40 if you are between jobs or in a rush.
6. 6Solving is only part of the interview. You also have to communicate well and be likeable. Rehearse that by streaming your practice on Twitch; put AlgoBlazer in the title and your stream shows up on our dashboard.
7. 7Use the global chat to find people to study with, or to ask for help.
