My experience with Scholarhat has been nothing short of Amazing! The training they offer is real time and Mr.Shailendra is always patient enough to answer all the candidate queries and even goes one step further to demo any special scenarios requested by the candidates. The best thing I found about Scholarhat is that, they allow you to attend sessions in a different batch if you want to repeat a particular session or if you have missed any particular session. I don't think there is any other training organization that provides this flexibility. Overall, a very informational session and definitely look forward to doing more trainings with Scholarhat. Will absolutely recommend to anyone looking for real time, hands on technical training!

Lakshmi Goyal

(CEO, Archwings Global (IT Services))

Real time project based training of “ScholarHat” is exceptional because their explanation and implementation on project helped me lot to work on company projects. Because their real-time exposure is really practical and same as development of projects. They have cleared all my concepts and cleared my doubts. By doing the project-based training, I have increased my confidence now I can develop something from scratch using AngularJS . I will suggest professions to go with them once you will remain with them.

Kiran Kumar Mohanty

(Senior Software Engineer at VeriFone India)

Shilendera sir given me best opportunity to improve my skills on Azure.I have learnt real time software development skills on these technologies ScholarHat provide better environment for improving latest technologies for better career prospect, especially to crack interview for next higher level of job.

Sarvesh kumar

(Sr. software developer)

I was on zero level when I have started my training with ScholarHat, Today I can say with my confidence that I am an expert on NodeJS and ReactJS technologies. I truly want to say thanks to ScholarHat for taking me on this Height in development, I have not been only developing my company project but also, I am capable to help my team to do the same. Especially I want to say Thanks to Mr. Shailendra Chauhan for his technique of teaching and combining concepts with example that the great things about his teaching pedagogy.

Shailendra Singh

(Software Consultant )

Data Structures and Algorithms in Java is the best training I've experienced. It offers comprehensive content, hands-on exercises, and expert instructors, making complex concepts easy to grasp and apply. Highly recommended!
