Will embedded systems training help an electrical student in his future?

Of course, the future of our technology is clearly moving towards embedded system only. To be clear, in real world application like automobile electronic systems, wireless Electronic door locks, automatic doors,.. etc are good examples of real time applications. Even in Industrial and Research also moving towards the same. We say Robotics but the basic of Robotic is nothing but the Embedded system. The definition of Embedded system " controlled by a real-time operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Wikipedia", to be short as per my definition, when you control any electrical equipment which do some physical work done by using a certain pre programmed codings and some logic with help of various Electronic components.

Now the answer to your question is, it is very good for an electrical engineer could study Embedded system will make his opportunity and scope very wide. And definitely will be a needed engineering in future.

I am an Electrical Engineer, passed out in 2018.  I took training from Kernel Masters, completed their six months Certified course as Embedded Systems Developer. I found it very practical and useful. Embedded Systems is not an entirely different field for us. You need to have proper programming skills to start with. In my training, I learnt everything from scratch, and finally, I got placed in Graphene Semiconductors in Bangalore.
If you want to go for training, I will recommend Kernel Masters, Hyderabad, as they teach everything from basic to advanced with good hands-on practicals and also best placements.
All the best!
