I think I can answer your question as we are from same organisation with same experience...3.5 years. I also had this doubt. I didn't receive many calls but when I got one interview which was relatively very simple to crack, my performance was embarassing. The experience stuck with me and I reached out to practically everyone...friends, friends of friends, seniors, juniors, college classmates, school classmates. I put myself out there, took what worked for me from everyone I got in touch with.
It's a process, you'll make mistakes and you have to learn from it and implement changes in your interview process or resume for that matter. It was a long process, but I learned a lot!
Today I'm happy to say that I was able to bag an offer.
I would say don't give up! Keep trying! Keep learning and you'll get there for sure. There are opportunities for everyone at any point of time. It may take time but you'll get there!
