If you want to go for further studies, then I would recommend you to go for BTech course via lateral entry. In this case, you will get admission directly to the 2nd year of BTech. Now you can choose or change the field of Engineering in your BTech which may not be of your diploma trade. But from a job perspective, it would be great if you can do BTech in CSE or IT as this fields have good salary ranges as well as the number of companies offering recruitments are also high. Now its your choice.

For Lateral entry the admission can be through later entry entrance or through merit score depending on your state.
