No, all our courses are independent, and you can enroll in any order based on your preferences.
&nbsp;
How is this course different from HLD?&nbsp;
The HLD course is more theoretical and includes demos. Its primary aim is to equip you with a thorough understanding of the concepts, preparing you for HLD interviews and providing insight into real-world system functionalities. HHLD focuses on implementing these systems. It prioritizes hands-on experience, ensuring you&#39;re equipped with practical skills and ready-to-use projects by the end of the course.
&nbsp;
How many projects will we work on? Can I add these to resume?&nbsp;
We will work on 3 end-to-end projects that you can add to your resume.
&nbsp;
Is this course for freshers or for experienced people?&nbsp;
This course is for anyone who wants to master HLD. Years of experience doesn&rsquo;t matter.
&nbsp;
Can I watch the classes only on the phone without a Laptop?&nbsp;
Yes, you can watch the classes on your phone without a laptop. However, it is a hands-on course. So, it is better to code as we proceed.
&nbsp;
Will you provide the code?&nbsp;
Yes!
&nbsp;
Where can I ask you doubts?&nbsp;
The discord community will always be active!
&nbsp;
What language will the course be taught in?&nbsp;
Everything will be taught in English.
&nbsp;
Do you have a mobile application?&nbsp;
