Data Structures and Algorithms (DSA)

Data Structures and Algorithms (DSA) is one of the most important skills that every computer science student must have. It is often seen that people with good knowledge of these technologies are better programmers than others and thus, crack the interviews of almost every tech giant.

Importance of DSA for placements:

• Coding Assessments: Most of the companies conduct coding assessments having problem on Data Structures and Algorithms to find the suitable candidate for the job. By conducting online assessments, companies judge the problem solving skills of the candidates.
• Coding Interviews: Many companies, especially top tech firms, prioritize DSA during technical interviews. Questions often involve arrays, linked lists, trees, graphs, sorting, searching, dynamic programming, etc.
• Aptitude Tests: Many companies have initial screening tests that focus heavily on algorithmic challenges.
• Problem-Solving: DSA enhances your ability to think logically and solve complex problems efficiently, which is a valued skill in any technical role.

How to prepare?

• Practice: Regularly solve problems on platforms like w3wiki, LeetCode, HackerRank and CodeSignal.
• Learn: Understand the theoretical concepts thoroughly. Books like “Introduction to Algorithms” by Cormen (CLRS) can be very helpful.
• Mock Interviews: Participate in mock interviews and competitive coding contests to simulate real interview scenarios.

Data Structures and Algorithms as well as Development, both are important in placements, but their importance vary with respect to the role you are aiming for and the company that you are targeting. Here is the breakdown of a detailed comparison that will give you a good idea of the emphasis you need to place in both:
