Feeling very lost with my job and life

Just a rant. I'm not sure if anyone feels the same way or only me. Working in the bank industry and almost OT every day. Though I had got a full-time job that pays decent well with around $4k (at least quite well based on my job scope). But somehow felt that I had almost learned nothing with this job, and my job scope is just basically very basic, which means even an intern or n-level cert can do my job. I don't need to study degree for this job though somehow my job required the candidates to get a degree.

My job scope involves scanning customer signatures, crop their signature into the system, batching some files, checking customer's singature profiles, and maybe some very basic data entry with Excel. Or replying email, that's all. Basically, I won't learn anything useful for this role or even useful for my future career.

Try to learn something new and maybe brush up my python programming course or sql during my free time which I learn abit during my part time uni but had forgottern most of it after I start working at this role. I need to OT almost every day, and basically, all my weekdays are gone. On weekends is the only free time for me to learn additional skills.

I'm trying to look for new jobs, but recently, the market is really bad, and some jobs require the candidate to have some technical knowledge. Even with part time degree I worked so hard for the past 5 years while working full time and manage to get my degree previously, but without the technical skills and the job experience the company wanted, I doubt any companies would want to hire. Just feel why I am in a sad state, and my life seems to be very stagnant, though I am trying my best to take up additional skills.

Though my team also includes a lot of undergraduate who just graduated from uni, they are not worse off than me since they just started their working life and most of them would be in their early 20s and gaining work experience. But for me, I am reaching 30s this year, and I felt that even if the jobs pay me quite ok, but still felt kinda lost about my life and what can I do about it.

I mean I don't mind doing OT but if OT includes doing stuffs that is not really helpful for my career or something that i am really not interested in, I felt that it will be just a waste of time so it means that I hate that I still need to OT to do something so menial. Quitting a job is not an option unless I can find another job, but I felt that finding a new job is really hard, especially when the economy is not doing well either.

Really hope how I could improve with my current state and any suggestions from redditors? I doubt i could such stuff to my colleagues either since the topic is quite sensitive. Anyone also having same issue with their work too?
