Data Structures: Every Programmer Should Know

Where Education meets Ambition

The unsung heroes of the programming world, data structures are the building blocks that hold your programs together. They determine how efficiently you can store and manipulate information, ultimately impacting your program's performance. So, whether you're a seasoned coder or just starting out, understanding data structures is a must!

What are Data Structures?

Imagine a library. Books are data, and the shelves are data structures. Just like a well-organized library allows you to find books quickly, efficient data structures ensure smooth retrieval and manipulation of information in your programs.

Data structures define how data is organized in computer memory. They specify not just the data itself, but also the relationships between different pieces of data and the operations (adding, removing, searching) that can be performed on them.

Why are Data Structures Important?

Using the right data structure for the job is crucial for several reasons:

Efficiency: Different data structures excel at different tasks. Choosing the right one can significantly impact how fast your program runs. For instance, searching a sorted array is much faster than searching an unsorted list.
Memory Management: Data structures help optimize memory usage. By understanding how data is stored, you can avoid wasting precious memory resources.
Problem-Solving: Data structures are fundamental tools for solving programming problems. They provide a foundation for designing algorithms, which are step-by-step instructions for solving a particular problem.

Common Data Structures:

The programming world boasts a rich arsenal of data structures, each with its strengths and weaknesses. Here's a glimpse into some popular ones:

Arrays: A fixed-size collection of elements, all of the same data type. Think of them as rows in a spreadsheet, where each row holds similar data. Arrays offer efficient random access, meaning you can jump directly to any element.
Linked Lists: A flexible data structure where elements are not stored contiguously in memory. Instead, each element points to the next one in the list, forming a chain. Linked lists are great for dynamic data (data that changes size frequently) as you can easily insert or remove elements without affecting the entire structure.
Stacks: Think of a stack of plates. You can only add or remove plates from the top. Stacks follow the LIFO (Last In, First Out) principle, making them ideal for implementing undo/redo functionality or keeping track of function calls.
Queues: Imagine a line at a coffee shop. People are served in the order they joined (FIFO - First In, First Out). Queues are perfect for processing tasks on a waitlist or simulating real-world queues.
Trees: Hierarchical data structures that resemble a tree. Elements (nodes) are connected with parent-child relationships. Trees are powerful for organizing sorted data and implementing efficient searching algorithms.

Most employers prefer hiring candidates that have good knowledge about the company. You can start your research by visiting the company website and its social media accounts to learn about its mission, business, and work culture. You may also want to go through employee reviews on third-party websites to get an insight into its employees' experiences. Knowing more about the company and the interviewer would help you align your response with the company culture and values.

If possible, also try to find out more about the interviewer on professional networking platforms so that you get familiar with their personality and temperament.

3. Revise your CV:

Once you have gained enough insight into the position and the company, customize your CV to match it with the job and the company.

Think about the questions the interviewer may ask and how you would respond to them. Search for common interview questions that are asked for the job profile you are interviewing for.

Some of the most asked questions besides domain related questions are:

· Tell us about yourself.

· Why do you want this job?

· What are your strengths and weaknesses?

· Where do you see yourself in another five years?

Double-check the destination displayed by your GPS device and arrange your mode of transport in advance.

In the absence of any such guidelines, you are required to attend a job interview in formal attire. If you are using perfume, deodorant or hair gel, make sure it is mild. Keeping your clothes and accessories (shoes, socks, belt, tie) ready a night before the interview can prevent unexpected hassles on the interview day.

7. Carry required documents:

Make sure to carry all the essential documents, including your CV, cover letter, reference letters, academic certificates and salary slips from your previous job if applicable. Organize them neatly in a file or folder. Keep a pen and paper handy so that you do not require to borrow them during the interview. If you need a laptop or tablet to show your work or make a presentation, be sure to carry one.

These are some of the tips that might help you ease out from the pressure of an interview. These tips will help you stand out from other candidates and make you confident for acing any interview.
