Why System Design?
System Design is the systematic approach that covers a wide range of engineering concepts and principles for designing scalable systems that are modular, reusable, and extensible.
Low-Level Design is the process of designing software components, interfaces, and modules of systems in a modular, reusable, extensible manner to meet the current/ future needs of any organization. High-Level Design digs into depth of all related variables, including architecture, required hardware/software components, how data travels and is stored throughout the system, and how caching is done to optimize the system for fast response times and reduced costs, etc. This includes choosing what kind of database to use, like Cassandra or MySQL or something else, and making choices like SQL vs. NoSQL.
A software engineer who understands both High Level and Low Level Design performs better. It enables an engineer to make architectural decisions to make the software system efficient and scalable while saving an organization's cost. It allows one to distinguish between available databases, e.g., MySQL, PostgreSQL, etc. It also enables one to find the best tool to solve a particular engineering challenge, with tools like Messaging Queues, Load Balancers, etc.
System Design will:
  • Enhance the quality of software systems developed by engineers
  • Save long-term engineers costs for a company
  • Make software systems able to handle changing product requirements and also handle large scale
  • To become a jack of systems design, you need to take into account the following when building a software system:
  • Understand the product requirements (current as well as future) and edge cases very well
  • Create and document software and System Design, which includes Class Diagrams, Schema Diagrams, Architectural High-Level Diagrams
  • Understand the pros and cons of every software system like Databases, Caches, etc., and when to use them
  • Key Highlights of the System Design Module in the Scaler Academy Program
    Become an expert at System Design with Scaler Academy. A necessary skill for any top software engineer, enable yourself to learn these important concepts with ease and swiftness.

    Read the reviews by Scaler Alumni on how Scaler Academy Program has helped become solid certified System Design Engineer
    I joined Scaler Academy to upskill myself for System Design and DSA. The way the curriculum was designed & the way we were engaged in the course is highly commendable. Before joining, the number of problems I solved was far too less. But, after joining Scaler I started solving around 350+ problems and this would have not been possible without the help of the instructors & TA's. A major shoutout to my mentor, he was so approachable that I didn't shy away from discussing if any problem came up. Assistance from Scaler's Talent Acquisition Team was highly helpful which made the interview process smooth and hassle-free.
    I enrolled in the six-month-long course, which was simply AWESOME. I appreciate the effort of Scaler team (Instructors, TA, Mentors, Recruiters). All of them helped me in boosting my confidence, skills & knowledge. I learned System Design, DS/Algo and other core subjects and the most important thing was I gained the confidence I needed to face any interview. Thankful to the Scaler organization for bringing such a learning platform into existence. Special thanks to my mentor who always encouraged & supported me and my recruiter for providing all the great opportunities & for being so supportive during the interview processes.
    Thanks to Scaler Academy, I am super excited and thrilled to share that I will be joining Brick&Bolt as a Software Developer. This has been possible as Scaler helped me upskill and improve my knowledge of DS Algorithm, System Design, and not forgetting the weekly lectures & daily assignments that helped me understand the concepts in a far better way. Thanks to Scaler team for creating this learning platform. Special thanks to all the mentors for teaching the DS concepts in-depth and the recruiters for guiding me throughout the interview process.
    I would love to thank Scaler Academy for improving my learning curve & skills in DS and System Design. The curriculum provided me with the structure I was looking for and that strengthened me in various aspects. Really very grateful to all the Scaler instructors for their guidance & support. Special thanks to the recruiter team who helped me through the onboarding process and also to all the amazing mentors.
    Thanks to Scaler Academy, I am excited to share with you that I will be joining Nurture.farm as a Software Engineer. This has been possible as Scaler helped me upskill and improve my knowledge of DSA and System Design. The weekly lectures along with the assignments helped me in understanding the concepts to the core. I would like to thank the team for providing such a great learning platform that Scaler is.

    Yes, all sections start at the same time but end at different times, depending on the duration of the course for that section. The Advanced section ends in 31 weeks, the Intermediate section ends in 39 weeks and the Beginner section ends in 47 weeks. Please note that the upcoming November batch would not accept applicants for the Beginner section. It would only accept applicants for the Intermediate and Advanced sections.
    Your eligibility for the Beginner, Intermediate or Advanced section is decided basis an entrance test.
    Depending on which section you are allotted, the duration of the course could range from 31 weeks to 47 weeks. This translates to 7 months to 11 months.
    Our tutors would teach you the concepts mentioned in the course curriculum and would take live classes 3 times a week. There would be different tutors teaching different topics
    Our tutors have built scalable systems in the past and understand the real-life importance of DSA and System Design, not just interview-relevant material. They have hands-on, real-life experience and don't just have theoretical knowledge. For more detail on our tutors, please visit www.scaler.com/academy
    We have 100+ Teaching Assistants that would solve your doubts in prompt-manner. These doubts could be related to the class content or regarding the assignments.
    Teaching Assistants (TAs) work closely with the tutors to help students with their assignments and homework. They answer students' doubts via chat and video call. You would interact with TA's regularly outside of the live-class sessions to get more hands-on problem solving experience.
    Teaching Assistants (TAs) mostly come from strong problem-solving backgrounds. They can be from a range of experiences but share a common interest towards coding and teaching alike.
    2 Teaching Assistants (TAs) are allotted per batch of 40-50 students. This ensures each student gets enough time with their TA and gets their queries resolved instantly.
    When a student has a doubt, he/she would raise a 'Help Request'. This 'Help Request' would be circulated within the peer group first in order to foster a sense of giving back and create a sense of community. In parallel, the Teaching Assistant is also alerted with regards to this 'Help Request'. The doubt can then be either clarified via the peer group or via the Teaching Assistants via text or via video call. If a video call is done, the Teaching Assistant can also share his/her screen to resolve the issue and help you understand the concept better. These video calls are done 1:1.
    The test will comprise of Multiple Choice Questions (MCQs) on the following topics:
    1. Logical reasoning and aptitude
    2. Basic mathematics (topics like permutation and combinations, probability etc.)
    3. Basic time complexity analysis
    4. Questions on figuring out the outputs of small code snippets (in any of C++/Java/Python)
    Yes! We have designed the test so that it can be easily taken on mobile as well. However for best results, we would advise you to take the test in a quiet setting with minimal disruptions.
    No, you do not need any special preparation for this test.
    However, if you would like, you could brush up on simple concepts like arrangement, derangement, and a few simple aptitude questions. For time complexity analysis and code comprehension questions, you could choose to practice questions like :
    1. https://www.interviewbit.com/problems/whilecmpl/
    2. https://www.interviewbit.com/problems/nestedcmpl2/
    3. https://www.interviewbit.com/problems/array2d/
    4. https://www.interviewbit.com/problems/whilecmpl/
    Mentors provide personalized advice on your career. They also help you with mock interviews, help with your resume and provide career advice. Mentors do 1:1 video calls with you for 30-60 mins each for each session. It is advisable to do 2 mentor sessions every month.
    Our mentors mostly work at tier 1 product companies and would be experienced software professionals. For more information, please visit www.scaler.com/mentor
    Based on your background, we offer a few mentors for you to choose from at the beginning of the course. You could choose 1 mentor of your choice from this pool. We try to ensure that your mentor is relatable to your background.
    We would entertain a request to change a mentor, but a change in mentor is done only on a case-by-case basis.
    We provide three kinds of placement support:
    1) Through our network with hundreds of employer partners, we would arrange for you to have access to job opportunities in order to accelerate your career or change companies.
    2) Our student, tutor and mentor community frequently posts job opportunities from their network as well, via ScalerChat (please visit www.scaler.com/mentor for details)
    3) Preparation assistance via mock interviews, resume reviews etc
    With the right teaching, curriculum and guidance, we are confident you will achieve your goals.
    Yes! We strive to help you prepare for your job interviews via mock interviews. Mock interviews can be done in two parts:
    1) Students can choose to do mock interviews with their mentors (as mentioned in the 'Mentor' section of these FAQs).
    2) We would connect you with a working professional in the company in which you would be interviewing. This would help you get in-depth knowledge of the company and do a more focused mock-interview to get prepared.
    Our employer partners range from technology MNCs (Multinational Corporations) to fast-growing startups to companies in the financial services space. Please visit www.scaler.com/mentor to learn more about where our alumni are placed.
    Employers hire for a wide variety of roles, including full-stack engineering and backend-engineering across a range of work experience. We would be careful to ensure that you apply to companies that match your qualifications and strengths.
    Employers typically hire engineers all through the year, depending on their requirements. When employers do approach us, we would make the opportunity visible to students in the batch. Students are welcome to apply for opportunities that interest them. Each opportunity would have a test associated with it and students would be referred based on their performance in these tests and other factors like attendance and their problem-solving percentage.
