There is a lot of scope in computer Science engineering. As first of al you need to undertand your passion, your desire that in which field u have interest. Being a computer engineer one have a variety of fields to choose. It can be:

• Data scientist
• Mobile app developer
• Game developer
• Cloud computing specialist
• Machine learning
• Robotics
• Web developer
• Ios developer
• System analyst
• System tester
• Database specialist
• Hacker
• Professor
• Coder

There are many fields in CSE you just need to show your interest.

If we talk about the scope of CS engineering then you can simply understand that CS is based on Coding and software development. Now the question comes regarding the scope of software development. So it is clearly visible that initially we were having large size TV, then came LCDs and then LEDs. Now there is more or less very less development possible in the hardware.
So now it's all about the software now as there's always something problem in any software to be addressed to make it more and more efficient.
So there is a vast and never ending scope in Computer Science Engineering.
You can also consider another example. You know that when internet came Google was not there initially but as it came into the market it just grew so rapidly. You know the value of Google today. Similarly there is a field in Computer Science i.e. Artificial intelligence. Nlw explaining about artificial intelligence is a bit difficult but you can understand that  the Google (example) of Artificial intelligence have not been developed till now.
So ultimately what I want to tell is that there is a vast scope in this field, vast.
