UPES vs Graphic Era, are these worth considering for tech careers?
Yes, indeed! Both the University of Petroleum and Energy Studies and Graphic Era University may be considered as options for tech careers, provided that the top-tier IIT/NIT level colleges are ruled out. Neither of them is known as one of the top colleges for CSE, but still students from these colleges receive good placements in software jobs provided that they develop solid coding skills.
Going by what's known about them, UPES is somewhat better branded and offers specialized courses in technology, although its tuition is relatively high. On the other hand, Graphic Era University seems less expensive, and the placements offered are fairly decent given the price tag. The coding environment in either case is determined mostly by your peer group and personal efforts.
As for the two colleges mentioned, yes, they are perfectly fine for tech careers, just don't expect to rely on them too much. Those who code actively, participate in internships and hackathons will get far in both places.
