How and What to Prepare

This is the nuts and bolts of how to use AlgoDaily to prepare for your upcoming interviews. This series of lessons covers the platform, algorithmic thinking, and provides additional resources beyond this course. It's highly recommended that you cover most of these lessons before continuing into concepts around the actual interview questions.

Beyond the Interview

This section is intended for folks trying to break into the software engineering field. If you're an experienced programmer looking to brush up on algorithms and data structures, we suggest you continue onto Pointers and Windows.

Pointers and Windows

Pointers and Windows covers the most common type of programming interview questions: those involving arrays, vectors, and references. We first cover the basics of strings and arrays, then we go through some important techniques, before launching you into some exercises to practice your knowledge.

Key Values

In this section, we cover the use of hash maps and hash tables. It gets an entire section for itself given how commonly you'll use them in real-world solutions. We also start introducing you to a powerful technique, dynamic programming, which can be used to solve some of the more challenging interview questions.

FIFO and LIFO

Knowledge of stacks and queues are incredibly helpful, as they serve as the foundation for many other future data structures and algorithms.

Node Manipulation

Let's start playing with some pointers! Linked lists can be confusing to start, by we'll show you step by step how to master them.

Climb Some Trees

Knowledge of Trees and tree traversal algorithms are required to understand the inner workings of databases, autocompletion, file directories, and much more. As usual, you'll get a strong overview of what you need to know before we jump into some problems.

Draw a Graph

In programming, we use graphs to model relationships between objects. Social media, map and GIS software, and the entire World Wide Web are built on top of these simple but foundational data structures.

Recursion

If you've studied Computer Science, you've heard about recursion before. Recursion is the process of defining a problem in terms of itself, and is surprisingly handy when it comes to cracking tough programming interviews.

Advanced Topics

Some more challenging concepts that you may or may not see on game day. Worth checking out if you have plenty of time.

Systems Design

Systems design is the process by which we as engineers make decisions regarding the elements of a complex application. These system elements-- such as the data models and structures, overall architecture, modules and components, and the different interfaces of those components-- have to be carefully contemplated to ensure speed, reliability, and stability down the line.

Language Specific

This section contains guides and walkthroughs addressing interview questions you might get that pertain to a language's characteristics, ecosystem, and community.

Frontend

User interfaces are becoming increasingly complex, especially on the web. Frontend engineering questions are now fair game for all software engineers, as your user experience will be compromised until you've mastered this area.

After the Offer

This is a section covering what to do after landing the offer, with some tips around choosing the right company for you and figuring out what's next.
