How to Learn DSA to Prepare for Your Coding Interviews?


Data structures and algorithms (DSA) are an integral part of every programmer’s set of skills used in interviews. Coding often forms the focus of these conversations, yet DSA should remain the fundamental knowledge for every programmer.

DSA is the fundamental upon which programming is developed. Learning and mastering this skill is as important as coding. Most programmers enroll in the best courses for data structures and algorithms to ensure their basic understanding of programming is correct.

It requires guidance, constant learning, and hard work to learn DSA correctly. Online DSA programs help learners study the basics and implement them in real-life use cases to strengthen their knowledge. They also prepare you for coding-based interviews, you can quickly gain placement.

Most interviewers judge a candidate based on their DSA knowledge. Companies such as Amazon, Microsoft, Google, etc. also evaluate candidates DSA skills. It is, therefore, very significant to learn DSA.

Before entering on your learning journey, ask yourself these questions:

  • How can I learn DSA effectively over time?
  • How can I crack the coding interview using DSA?
  • How much time do you require to get ready for coding interviews?
  • How do you learn DSA quickly?
  • What essential concepts and methods should I know?

Answering these questions can help you gain better insights about your current state. You must plan accordingly and maintain the learning flow.

Let’s understand more about how you should solve these questions.

1.  Finding the motivation to start learning DSA

You must first understand how learning data structures and algorithms can be beneficial. Once you understand why DSA is essential in your coding career, you can gain an appreciation of its real-life applications. If you wish to develop long-term knowledge in DSA then understanding its significance is of vital importance.

  • As a programmer, every learned DSA concept is essential to you. You can never know which concept can be useful in certain situations.
  • You must learn from your failures. DSA is a complex topic, so many stop learning it after a while. However, you must be ready to face failures while implementing codes and learn from them.
  • Problem-solving is the key area. You must focus on developing this skill. As you become better at problem-solving, your confidence will increase.

2.  Learning DSA for coding interviews

Next, you have to start learning the significant concepts in DSA. You may focus on topics that are essential for coding interviews. You can prepare yourself through constant practice with interview questions. You may find company-specific mock interviews in the best courses for data structures and algorithms.

You must learn these concepts:

  • Fundamentals of Programming
  • Fundamentals of Algorithms
  • Linear
  • Algorithm Design Techniques
  • Non-Linear Data Structures

3.  Finding learning resources

Find helpful learning resources, such as online DSA programs, that turn learners into professionals. Some best courses for data structures and algorithms are available online. Find a nice program to study DSA.

  • While searching for online courses, check their learning modules and other facilities they offer.
  • The course must prepare you for placements through mock interviews. They should provide interview questions, so learners can practice and hone their skills before placements.
  • Experienced mentors offer great knowledge and insights into the industry, so make sure you learn from expert mentors.
  • It is also important that the course offers practical training along with mentors. Solving real-world problems is a great way to develop problem-solving skills.

In addition to online courses, you can start learning through books and PDFs like Gayle Laakmann McDowell’s Cracking the Coding Interview. Coding sites like Leetcode are also helpful resources to practice your coding skills.

4.  Find a learning network

Often, it can become difficult to solve problems by yourself. You can get the help of your peers and form learning groups. It helps you learn quickly when you study with others and learn more as a result. You can solve problems easily and learn complex topics.

Create groups of 2–3 peers who share similar interests and hold weekly sessions to study together. Being in this type of collaborative environment can help you learn quickly and easily. You may identify your own strengths and limitations to work on advancing your learning.

You may find some online learning communities consisting of programmers from different backgrounds. Furthermore, you can resolve doubts and interact with them to solve problems.

5.  Start preparing for interviews

To crack interview questions, you can start practicing behavioral interviews. Many candidates appearing for interviews think behavioral interviews are less important. But, preparing for these types of interviews can help a candidate stand apart from others.

The recruiters assess your problem-solving, decision-making, and communication skills through behavioral interviews. One can practice mock evaluations through the best courses for data structures and algorithms. Take the feedback from experts conducting the interviews and improve in the areas you lack.

Here are some tips to help you:

  • Start practicing the implementation of a problem on paper. It helps save time and work quickly on any given issue.
  • Communicate clearly with the interviewer. Discussion about how you approach problems is invaluable practice in problem-solving.
  • While working in a group setting, try to be an ideal teammate and solve problems together. This shows the interviewer that you can work effectively within a team.


Learning DSA can become boring as you move to more complex concepts. You require the guidance of an expert mentor to help you become a better coder. Online DSA programs help offer the best mentors with relevant learning materials, for your professional career outlook.

The DSA Program is among the best courses for data structures and algorithms. Mentors provide expert guidance in live classes, learners participate in practical problem-solving sessions with real-world applications, and the program offers IBM and Microsoft certifications.

You can join live discussions with your peers on the course. The course will also prepare you for coding interviews through mock interviews, resume preparation, and more. You will solve company-specific coding questions with the help of experienced mentors.
