I have attended Shailendra Sir class for Asp.Net MVC with Angular2 & 4 He cleared many concepts of MVC and Angular and also tells us about the real life scenario where you can use these concepts. He answers whatever questions are raised during training course by students. He never gets irritated. I have cleared many basic concepts of web application development also.. which are very necessary to know when you are gradually moving to bigger companies. I have attended many training session but this training is different than others and i think more beneficial than others. I recommend professionals to join this training session.

First of all, I would like to thank ScholarHat for everything. Here is my experience in ScholarHat - "When I came to know about ScholarHat, honestly I didn't have much idea about Data Structures and was looking for a job. So I thought it would be a better option to join here and get some knowledge about real-time projects and a few interviews, which would be a big thing for me. Then I was assured by the staff from the ScholarHat and joined. From day one I felt a different energetic atmosphere in the classroom. And about the staff all are well educated, trained and also very friendly to everyone, as a student which helped me a lot, they never shown any irritation even though I was asking same things repeatedly. The main thing is that all the syllabus covered up in a proper manner, so that a student can understand each things about the training. And thanks for providing some important seminars which helped me a lot to crack an interview. Thank you ScholarHat for making my career". I have never taken it so far in my life time, and day by day it’s getting better for me. I have got confidence in facing Xamarin interviews and learned lot of new real-time scenario. Keep rocking ScholarHat, your team is doing great job.. Way to go..

It's a great experience to be part of ScholarHat. this Training really helps me for improving my enhancements skills professionally also. If I talk about interview purpose it's really a great great opportunity because in training class this was my personal experience that Sir won't leave a single scenario that Interviewer going to ask you. He covers all the concepts theoretical as more focused on practical. If you really want to beat Interview and get good job and hike join ScholarHat.
