Feeling under-valued

I'm a final year student studying engineering in a tier 3 college, I always indulged in many extra circular activities, l published paper, club activities, was a facilitator conducted many events related to technology, also made awesome project throughout my engineering life, was also awarded for my projects college wise also in state wise under specific domain, no matter what, I always Delivered my part of the work on time, and even I was excellent in my academics, maintaining above 9 cgpa, I did all such things so that I can get a nice offer at some company, but I really hated how it turned out, incampus needs luck than skill, people will copy in there OA, and I've seen so many got there offers even though they did nothing impressive, I've seen people with no tech knowledge bag up a huge package, while I would get rejected everytime. I am really depressed I feel like that my efforts are being made a joke by all the selected people. I feel that I've wasted my engineering life with all those extra activities.
