Coding Ninjas helped me explore various opportunities when I was in doubt during my 4th semester. Ankush sir is the best mentor I've come across in my life, gradually I moved on to Web Development and Competitive Programming course which helped me sharpen my skills and achieve an offer at Amazon.

The best part about this institute is its instructors. The way they all teach is really engrossing and you learn everything pretty well. The course content is nicely structured to make the learning curve smooth.

Anjali Garg

Google

Software Engineer

I enrolled in Coding Ninjas' competitive programming track which consisted of 3 courses: Introduction to C++, Data structures and Algorithms with C++ and Competitive programming. All the courses are well structured and taught by excellent instructors. Apart from this, I also loved the CodeStudio practice platform of Coding Ninjas. I would strongly recommend one to take data structures and algorithms course here at Coding Ninjas if one is aiming for big product based companies like Amazon, Facebook, Intel, Qualcomm etc.

Raghuvansh Raj

Visa

Software Engineer

While I was experiencing the course, I constantly felt my confidence with respect to solving problems grow. I think that's what matters at the end of the day, the confidence that one can solve a problem and clarity in terms of approach. Coding Ninjas helped me inculcate both into my competitive programming journey because of which I was able to bag an internship at Visa.

Samarth Sahu

Coding ninjas journey was a very fulfilling one and I would definitely recommend it to my juniors. The lectures and practice are of very high quality and are the right amount to secure any software engineering job/internship.
