What Our Students Say

Coding Blocks alumni on what changed for them, in their own words.

CB is an excellent place for both refining your skills in a known domain & venturing into a new one. Its well-structured courses & well-informed teachers make the process considerably easy. I am grateful to it for augmenting my skill set.
Tuhina Singh Working at Goldman Sachs Group
It was an amazing experience and the best decision of my life to take up the Algo++ course this summer. I can't begin to thank enough the coding blocks' team and my teacher prateek bhaiya for showing the right path. What i learned in the course helped me at every moment of my interview process. It was literally unbelievable how this course changed me completely in those 5 weeks.
Kartik Shinghal Interned at Microsoft
Coding Blocks helped in gaining enough experience to get internships at giants like Google and Rubrik.
Anshul Mittal Interned at Google
One summer ago, I was just another COE student trying to swim through the vast expanse of the domain without much success. Fortunately, I made a good decision to join Coding Blocks for Algo++ course. Can't be thankful enough to our course instructor, Prateek Bhaiyya for making the topics seem effortless. The environment during the classes was competitive so one had to stay on his/her toes. Big Big thank you to everyone at Coding Blocks.
Kaustabh Kakoty Interned at Microsoft
I am quite fortunate to have taken two courses from Coding Blocks. Before joining Launchpad, I knew only basic programming. So many topics were covered in-depth, that the knowledge and skill I gained helped me clear my interviews. My crystal clear concepts, as well as familiarity with data structures enabled me to clear all three rounds in the very first campus interview I appeared for. The Android app development course super awesome. Arnav bhaiya is a true mentor, with great knowledge in the fields he teaches. I always found myself asking doubts with Deepak bhaiya (Launchpad mentor) and Arnav bhaiya(Android mentor). They guided me in all possible ways. After completion of android app development, I was able to make quite significant apps, and now I find myself contributing to open source quite frequently. Thanks to Coding Blocks for all the great experience they provided me. Involvement with coding blocks have always been helpful. Their guidance has helped me secure internship at Amazon (offcampus) and Samsung Bangalore (oncampus).

Coding Blocks has played a major role both in my career development and strengthening my programming basics. Launchpad helped me in building the basic blocks and Pandora (Android Development) made me able to develop live projects in the production environment. Guidance provided by Coding Blocks mentors made really made a great impact and helped me gained skills that were beneficial in an interview process. They guided me in all possible ways. After completion of android app development, I was able to make quite significant apps, and now I find myself contributing to open source quite frequently. After that, I applied for Associate Android Developer Certificate and then I was able to clear test and the walkout interview. Thanks to Coding Blocks for all the great experience, they provided me.
Darsh Pratap Interned at Deutsche Bank
I love Coding Blocks because it helped me to get familiar to syntaxes. Helped me to implement the code and not just logic. Salesforce is like a dream come true. Thanks a lot Coding Blocks.

Teachers at Coding Blocks are the best you can get. From taking my first step towards coding to getting a gold medal on Hackerrank, from my first android application published on Play Store to winning Smart India Hackathon and from being a TA at Coding Blocks to getting my internship at VISA, they were always there as mentors to provide support and direction. Bring in your dreams and heart full of dedication and here at Coding Blocks, they'll turn them into reality...
Aarnav Jindal Interned at Visa
Joining Coding Blocks will remain as the best decision of my life.Manmohan bhaiya since days of VMC has been guiding me and he was one of those who encouraged me to join ICE at NSIT and learn programming side by side.I was a complete noob in programming but the journey of scoring low marks in Basics of Programming course to get placed in DELL in third year itself has been quite amazing.The environment which Coding Blocks is such that you will just fall in love with coding.Finally I would like to thank Munna Bhaiya, Priyanshu Bhaiya, Prateek Bhaiya, Deepak Bhaiya and all the other members of Coding Blocks who work so hard just to nurture our career.
