What is Data Structures and Algorithms

Best resources to prepare for DSA and tech interviews

This article of Accio tech tips focuses on providing the best resources to help you prepare for Data Structures and Algorithms as well as your upcoming tech interviews. 

Almost every tech company's hiring process passes through the stages of coding rounds as well as tech interviews. So it is very essential to be well prepared for both of them to ace the interviews of the prominent tech giants. In this discussion of exploring some of the best resources, we shall be mentioning details about three major aspects:

Data Structures and Algorithms, Computer Science fundamentals and Tech interviews. 

Starting with Data structures and Algorithms, amongst the vast array of resources available, we will discuss the utility and importance of three major resources for the preparation of data structures and algorithms.

1. Geeksforgeeks - Geeksforgeeks is considered to be one of the best platforms that contain solutions to almost every DSA problem, simplified in a very conceptual and precise way. One can submit their solutions for most of the problems and hence it also qualifies as a great platform to kickstart your DSA journey. It contains a list of 'must-do' questions that had been previously asked in various companies' coding rounds and tech interviews. Solving these questions will strengthen your basics and help you approach similar questions more efficiently in the actual selection process.

2. Leetcode - Leetcode is one of the well-known programming platforms that has a collection of over 2100 problems across all the DSA topics. It organizes weekly contests in a format that is similar to the type that is asked in the coding rounds of various tech giants like Google, Microsoft, Flipkart, Intuit, and many more. It provides a structured format of questions to help you master your skills and they also have a discussion panel that contains optimal solutions from other users.

3. InterviewBit - InterviewBit is one of those resources that contains coding questions that are frequently asked in coding rounds and tech interviews. Each question is associated with a 'company tag', where the name of the company represents the corresponding question that was asked by them earlier. This gives a better idea for understanding the selection process of each company distinctly. All the questions are from DSA and your score for attempting that question is impacted relative to the wrong submissions and time it took to solve that question. This will help you write the correct code in the lowest time possible since accuracy and time are both very important factors in any coding round.
