Our Students Reviews

Scholarhat has brought a new revolution in e-learning which reform the way of learning. Scholarhat training best ever training i have gone through. It's compliantly changed my programming approach while developing software application. i'm feeling proud while writhing this testimonial.

Rajat Sharma

(Sr. Software Engineer)

I believe that Scholarhat is the best place for learning and updating ourselves moreover overcome from all issues that are face during development ...!! I come to know about Scholarhat innovative way of providing real time project based training in 2014 through one of my friend who have taken class from Scholarhat, during that time I started my career as a UI developer, my friend who have taken training in Angular JS working with HCL technology. Now after one and half year I have been looking for changing my job profile so that I have joined Scholarhat again for updating MEAN Stack Developer. Few words to Shailendra Sir, Thank you very much sir for giving me a precious guidance by explaining through various real world scenario.

Kuldeep Kr. Shakya

(Sr. Project Executive)

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.
