How long does it take to prepare for a System Design Interview?

 System design interviews are an essential part of software engineering jobs. But unlike other interviews, like coding interviews, a system design interview can have correct answers more than one in count. So, it becomes more crucial to prepare for it as you must know all the outcomes and the most efficient one among them. 


Candidates often question how long it takes to prepare for a system design interview. A simple short answer to it is 4-10 weeks. But it is when you start from scratch and have 2-3 hours to prepare. But if you understand the basics, the time can come to 3-4 weeks. 


However, the exact time can only be estimated considering other factors. So, let's go through all the essential factors when calculating the time to prepare for a system design interview and how to prepare for the interview with a system design course online. We will also touch upon the concept of the structure of the c program.


What are the factors to consider when preparing for a system design interview?


To prepare for a system design interview, there are many factors to undertake, such as your level of skills, the role you are applying for, and some of your personal factors. Let's look at these factors and how they affect your preparation time. 


  1. Level of skills you have

Your skill level is the first factor in deciding the time you need to prepare for the interview. If you are a student without hands-on experience, you will probably take more time to prepare for the interview. On the other hand, if you have some knowledge in the field of software engineering from a job or an internship, it will take less time. 


  1. Role that you are applying for

Every career option has various levels or roles aligned in a hierarchical structure. Similarly, you will find many roles in the software development field. Based on the position you have applied for or want to apply for, there will be a difference in the syllabus for the interview.


Simply put, if you are applying for a higher position, you must cover a broader range of topics and concepts. Here is a brief about what you should know for the interviews for different roles in system design. 


  • Junior and mid-level roles


For a junior or mid-level software engineer job, you must understand the basics of the system. Moreover, you should practice the concepts in a way that you will be able to explain them to others. 


  • Senior Job roles


For a senior-level job, you may not ask about the basics much. But still, you should cover the basics. Moreover, the components of system design and interactions between them must be understood for a senior-level job role. 


In addition, the interviewers may also ask anything about the lifecycle of a system design procedure. So, it is also a must to know about the area. 


  1. Personal Factors

Other than the above two factors, personal factors or circumstances also decide the time for the preparation. Firstly, all people can't be the same, nor can their learning abilities. You can either be a slow learner, a fast learner, or a learner with a medium pace. So, the time will differ based on how instantly you can process the information you read or see. 


Secondly, the schedule of a person is also a contributing factor. For example, if you are a student, you most likely have more time to give to your preparation. On the other hand, a candidate currently in a job may be unable to take a lot of time for the preparation. 


How do you prepare for system design?


Enrolling in a system design course online is the best way to prepare for system design. A System design course is structured in a way that explains every component and concept of system design. Moreover, an online system design course can be better for those currently working in a job or regularly attending college.

What are the 5 types of inheritance?

Image
  The concept of inheritance is considered among the most crucial concepts of object-oriented programming. Inheritance in Java is considered as a process where one class inherits the property of its parent class. When we simply define inheritance, we call it the capability of a class that derives the properties or features of other classes. The new class will be created as the ‘ derived class’ and the existing class will be known as base or parent class. Talking about the types of inheritance, it is generally of five types. Here, in this blog we are going to discuss all these inheritance types in detail with the help of examples. Without any ado, let’s get started! Types of inheritance In case of inheritance, one class derives the properties from its parent class. Here, any new class will be derived from its existing class. This new class is the derived class and our current class will be termed as the base class. When we talk about inheritance in Java, there are mainly five types ...

Remove duplicates from a sorted linked list

Image
Introduction Before reading this article, It is recommended to have an understanding of the linked list and its implementation and some basic operations on the linked list. Problem Description Create a function that takes a non-descending list and removes any duplicate nodes. Only one traversal of the list is necessary. Eg. Consider the given linked list: 1->1->1->2->2->3, the function is expected to convert the linked list into 1->2->3. In this article, we will extensively discuss the Label Control in C# & how to  remove duplicates from sorted doubly linked list .  Important:  We are supposed to delete only the duplicates i.e. only one copy of nodes should be there. Intuition:  The biggest hint given is that the list is sorted or non-decreasing in nature. From this, we can deduce that if duplicates are present, then it has to be the next one in the chain. The ideal way to approach this problem is to simply loop through the first value i...
