The motive is to help the viewers of the Coding Decoded Channel land the job of their dreams and become a better engineer! It is a one stop solution for all your technical knowledge. Its primary focus is to help viewers build strong
- Data structures and algorithm concepts
- Coding Aptitude
- System Design
- Interviewing Aptitude and process
- Deciphering Interviewer's mindset
- Motivational talks
In the last year we have solved 600+ problems and published their videos. We daily publish solutions to leetcode monthly challenges. We also solve leetcode weekly contest questions as well.
Each video has a pictorial representation of the algorithm, test cases walk through and cherry on top is live coding session.
Hard work paid off. We have already reached our first milestone of 1k+ subscribers and hope to build the largest coding community.
If you also intend to get a job of your dreams, come join us, and become our companion. We will together make it possible.
Coding Decoded Channel All the videos are hosted here.
Coding Decoded DiscordIt is a place where peers of the community help each other with their queries, schedule mock interviews among themselves and bring in a little humour.
