Important Subjects For Placement Preparation

Important Subjects For Placement

If you also aspire to be a good Software Engineer, you should learn all these subjects. In this blog, I will discuss all of the subjects necessary to land off-campus interviews. I hope you like it.

DSA or Development alone will not earn you a position in Product Based Company.Yes, Yes, DSA is necessary, but it will not get you a job as you must also understand OOPs concepts, DBMS, Computer Networks, Operating Systems, and, most importantly, System Design.

Important Subjects

Data Structures And Algorithms (DSA)

DSA is a must to crack any SDE role. It helps you solve real-world problems. For example, sets are of great use to store distinct elements in sorted order. For sorting any data, there are several algorithms available. Depending on the type of data, a sorting algorithm is chosen. There are several factors that make an algorithm efficient, such as Time complexity and Space complexity. So, it is very important to learn and understand when and how to implement an algorithm based on the given problem statements.

Object Oriented Programming (OOP)

OOPs play an important role in deciding how a code should be structured and in any interview. C++ and Java are popular languages that support object-oriented programming. Concepts like Class, Object, Inheritance, Encapsulation, Polymorphism, Data Abstraction, etc. are very important.

Operating System

An operating system can be accurately defined as a program that manages the hardware and software applications on a computer. When you switch on the target device, the operating system is activated. It comprises all of the processes that help us gain access to the technology and control it. And hence, it is very important to learn.

Database Management System

Databases are used in almost every application to store data. There are several databases available now, and different databases have different benefits. A few such databases are MongoDB, SQL databases, Firebase Firestore, Firebase Realtime Database, etc. In interviews, SQL queries and good knowledge of databases are very important.

Computer Networks

Well, not all companies ask networking-based questions. Companies like Cisco, Juniper Networks, etc. mostly ask questions about Computer Networks. To get jobs like network engineer, network consultant, and cloud engineer, computer networks is essential to learn and understand.

System Design

It is a very important subject asked by most product based companies. System design is the process of defining the components, architecture, and data for a system to meet specific requirements, such as scalability, performance, and availability.

Conclusion

If you want to succeed in interviews for product-based companies, you must know these subjects. Nowadays, many people like working for product-based companies since they provide exciting perks and salary packages. However, this does not imply that working for startups, service-based companies, or other organisations is not cool. Every job has benefits and drawbacks. These subjects are needed if you want to land a job at a product-based company.
