[@jasonhumphrey2464]

you're giving out great recommendations & perspective

[@SajeelCodes]

I think

[@bryanedds8922]

Algorithms, no. Data structures, YES. Unfortunately, interviewers usually only care about the first.

[@robinsingh4492]

I agree with you but this could only be possible in countries like US,CA,AUS,UK etc because these countries are very much advanced in IT sectors and have tons of jobs available. But In country like India where unemployment is high the competition is also very high. Even the smallest companies in India checks your rank on Competitive programming websites along with the projects so that's why In India DS&A is a must to land your first job hope you get my point. It depends on which country you are. Even China has a huge population tho but better IT sector than India.

Once you get a job you won't ever really need to implement these data structures yourself, but you should still have a good understanding of how they work so you can choose the right one to use. If you don't know when to use an array and when to use a linked list then you're not going to be a good programmer.

Put it this way: No one has ever become a worse programmer because they have a strong understanding of DS and Algorithms. In many cases, even if you don't "need it" for your day to day job, in the longer term it makes you a better programmer.

Hi Andy, during my years in university, the teacher always told us, focus on the algorithm, OOP, and design pattern. Never distract yourself by fancy GUI. So, I spent almost 6 years in console programming. Implement data structure by C/JAVA. What I have learnt was that if you got a crystal understanding on algorithm, OOP and Design pattern, you were sort of genuine high level geek. You even know how the CPU works. My teacher also told us, that programming was art. Be respectful. Never let your programming career by money driven, let it driven by exploring the unknown world. Then u will make some contribution to the industry.

[@chillydoog]

It's great to hear about your dedication to mastering algorithms, OOP, and design patterns during your university years. These fundamental concepts are indeed essential for becoming a skilled programmer and understanding the underlying principles of software development. Having a strong foundation in algorithmic thinking allows you to solve complex problems efficiently and optimize code performance. Understanding OOP helps in designing modular, reusable, and maintainable code structures, while design patterns provide proven solutions to common software design problems. Console programming can be an excellent way to focus on these core concepts without getting distracted by the complexities of GUI development. It allows you to concentrate on the logic and functionality of your programs. Your teacher's advice about programming being an art and not being solely driven by money is valuable. A genuine passion for exploring and pushing the boundaries of your knowledge can lead to significant contributions to the industry and personal growth as a programmer. It's essential to find joy and fulfillment in the process of learning, problem-solving, and creating software. However, it's worth mentioning that different programmers have diverse interests and career paths. While some may focus on low-level optimizations and understanding CPU architectures, others may specialize in different areas such as web development, mobile app development, or data science. The programming field offers a wide range of opportunities, and it's important to find the areas that resonate with your interests and aspirations. Remember to maintain a balance between honing your technical skills and exploring new horizons in programming. Continuous learning, staying updated with industry trends, and being open to new challenges will help you grow and make meaningful contributions in the ever-evolving world of software development.

In the past 4 days, I had two screening interviews with two different small companies and both were asking me medium-to-hard algorithms that are being asked in Facebook and Google. I did my best but I guess it's not fair for a junior developer like me to be familiar with these types of algorithms because if I am really that good why wouldn't I go work for FANG instead of these small companies and get a higher salary. They should calm down and ask questions at their level not giving algorithms about inverting a binary tree or searching for elements in the matrix.

Thanks alot for the explanation Andy. I got a job vacancy alert in Front-end web development Using HTML CSS and JavaScript and Angular which I'm good at sort from the deep JS concepts and I decided to pursue it.

I went through most of the questions in their demo test and all I could see there was data structures and algorithms, binary tree search etc. I haven't studied this part of JavaScript before because I knew I wasn't ready. But now it seems like they wouldn't care if I'm going to use it or not relating to the job description. I'm quite confused and don't know what to do. I'd appreciate if you can give me some tip.

[@ArtumTsumia]

Data Structure and Algorithms should come somewhat naturally during the learning process. When you start learning, things will be simpler and they might not naturally emerge, but as you develop more complex projects, the more basic structures will occur somewhat naturally (even if you aren't fully aware of them). Picking up a few sources that give you a high level look into structures, even if you don't go out of your way to implement all of them, will help you identify where they'll be useful or where you've already started utilizing more rudimentary versions. So not strictly necessary, but once you've got a reasonable understanding, they should be part of that next step. If you're at the stage of looking for a job, they should probably be on your plate already, not just to set yourself above other programmers, but because it's just one of the next basic steps. While it's not easy to identify the complexity of certain aspects when you're starting out, it's best to focus on learning things in order of complexity, as it'll lead to a stronger base as you continue to grow. In this way, you might find that you've implemented a primitive state machine, which you can refine once you're aware of it . As you continue to learn, you'll discover ways to further refine it. What might have started as a collection of conditional statements, might turn into a queue of function calls, with the various fundamentals leading you to those kind of refinements.

What you are explaining (quite clearly I admit) is not about understanding data structures and algorithms; it is about what you need to know to get a programming job. The two are not the same. Getting a programming job relies on how familiar you are with using the latest "hot" programming / scripting idioms to put together apps regardless of what data structures or algorithms they rely on. Now, if you wish to understand what the stuff they rely on is about, and why it is useful to do so, I invite you to peruse this presentation I made 24 years ago to an audience of non-programmers entitled "Is Computer Programming a Science?": hassan-ait-kaci.net/pdf/sfupres.pdf

Do you need to learn data structures and algorithms to get a job as a software developer? No. Do you need to learn them to be a *good* software developer? Absolutely. Even beyond just the coding benefits, it helps immensely in other areas. Knowledge of algorithms and how to efficiently design them, for instance, can help you identify processes in your organization that could benefit tremendously from new software. Just recently, I discovered a process some of my colleagues engaged in that takes them about 2-3 weeks to complete. Why? Because what they're trying to do is solve a version of the Knapsack Problem manually. Within about a week, I was able to apply what I've learned about efficient algorithmic design and develop a heuristic program that accomplished the same task with a runtime of about 2 minutes. Studying algorithms not only helped me write efficient code, but also contributed to my ability to identify an opportunity for improvement that no one else at my company could. Tl;dr: Data Structures and Algorithms are key pieces every programmer should know if they want to maximize their contributions and abilities.
