Aviation Engineering Grad.

Hello, I have done BEng Aviation Engineering and have been looking for work for quite a good while now have been through giving up and not in between for many times that I have not applied to anything, confidence has hit very low. Any advice to look up on skills? I have been learning excel for a while now but I only have the online version so have been trying to be good at it not a pro but learning. What more should I do?

I am interested in Operations be it airport or airline.

Have also messaged many people on LinkedIn for some guidance but it always ends up on either look at the careers page or ghosting.

Please advise me also I am aware I have lost time on giving up but couldn’t help it.
