Why companies like Amazon, Microsoft, Google focuses on Data Structures and Algorithms : Answered

It’s Summertime and the placement season is in full swing! There are many product-based companies that recruit during this time like Adobe, Amazon, Microsoft, Google, etc. However, most of the interviews for technical roles in these companies are focused on measuring the Data Structures and Algorithms knowledge of the candidates.

So the question arises:

Why do Product Based Companies place so much emphasis on Data Structures and Algorithms?

Software Product Based Companies normally create products that are related to software. So it stands to reason that they require quality Software Developers to handle the development process for the software. The pay-scale of Software Developers has increased a lot in recent times globally. According to the report by glassdoor, the average base pay of Software Developers in India is found to be around 10 Lakhs per annum. The average base of software developers ranges from Rs. 365,000 to Rs 1,709,000 per year. (With Product Based Companies occupying the higher end of the spectrum)

However, there is an acute shortage of well-qualified Software developers in India. According to the National Employability Report by Aspiring Minds, only 3.84% of engineers are employable in software-related jobs at startups. That is where Data Structures and Algorithms come in. They are so important in Product Based Companies interviews as they are the hallmark of any good Software Developer.

In addition to that, there are multiple reasons why Product Based Companies place so much emphasis on Data Structures and Algorithms as stated below:

  1. Data Structures and Algorithms demonstrate the problem-solving ability of a candidate. There is no room to craft elaborate stories and this means that either the candidate can solve the problem or they can’t.
  2. Questions based on Data Structures and Algorithms can be scaled up or down according to the knowledge level of the candidate. This means that a variety of candidates can be tested using roughly the same problems.
  3. Data Structures and Algorithms are used to test the analytical skills of the candidates as they are a useful tool to pick out the underlying algorithms in real-world problems and solve them efficiently.
  4. Data Structures and Algorithms are the fundamentals of Software Development. They remain the same no matter what new technology is used and that puts the focus on the problem rather than the technology in the interview process.

Learning Data Structures and Algorithms

Now that we have established that Data Structures and Algorithms are important for interviews in Product Based Companies, let’s focus on learning them.

Bad programmers worry about the code. Good programmers worry about data structures and their relationships.

While learning Data Structures and Algorithms, it is best to start small with simpler topics and then move on to more and more complex topics. Some of the basic data structures are Arrays, Linked Lists, Stacks, Queues, etc. while some of the basic algorithms are Sorting, Searching, etc.

Some of the major problems that can appear while learning Data Structures and Algorithms are:

  • Lack of guidance
    There is no clear guidance while learning Data Structures and Algorithms. There are numerous topics within these umbrella terms with no specific guidelines about which topics would be more useful for different Product Based Companies. This situation can be quite confusing, especially for a beginner.
  • No idea from where to start learning
    Even if the necessary topics in Data Structures and Algorithms are known, the sheer amount of them leads to a lot of confusion. Most beginners have no idea from where to start learning or even what chronological order to follow while learning.

To solve the above problems, we at GeeksforGeeks have designed a number of online courses to learn Data Structures and Algorithms at affordable prices. One of the latest course created by us is named Placement 100. The prefix “100” in the name of the course indicates that this course aims to get you 100% placement ready. This course covers Data Structures and Algorithms along with other subjects in order to completely prepare you for placements in product-based companies. Placement 100 is a 6 months program comprising of an online course, assessment exam and placement assistance for top performers.
