The finance sector has been good to me, worked at the same place for 8 years, was well paid, got laid off due to cutbacks as my skills were not needed anymore, but got a good deal and am now at another finance company earning more and doing more interesting stuff.
I don't mind, I have two trade school educations in IT, both dealing with networks, one also focusing on Windows servers, active directory, stuff like that, the other focused on Linux.
I then started working at helpdesks, and at my last job I started as a helpdesk technician, and wuickly got tasked with managing their Linux systems in addition to being part of an advanced internal helpdesk dealing with everything from ordering equipment to configuring AD policies and Microsoft 365 systems while also being a VIP tech for the top managment.
The VIPs and Linux stuff was never the main focus, but I learned a lot, and combine that with my personallity of being patient and positive I had a great time and made a huge impact on the company.
I can't say too much about my current place of work due to NDA, but there is a lot of work that needs to be done, and I have tried to hit the ground running.
Please also not that this is a European perspective.
If you want advice on what you should focus on to improve your chances, I can share a few insights...
Right now, IT is moving everything to the cloud, you don't have to like it, but you have to deal with it.
This does not mean that traditional skills from running servers are useless, it jist means you need to apply them in other ways.
Networking can't be completely run in the cloud, even if the management portal is located in the cloud, you still need switches, routers, access points and firewalls on site.
Linux will suddenly pop up, learn how to navigate it, how to manage files, especially permissions, learn the basics of vi and nano, vi exists on every normal Linux system, nano is not uncommon and is far easier, but it is not uncommon to find it missing on servers.
Working with AI is a fad right now, it will be of less improtance in the next years, but new AI and LLMs are constantly being improved and users will learn how to use the tool more effectively, learn how to use it now, so that later when it matters far more you will be prepared.
Most improtantly of all, have an artistic hobby outside the computer, it is increadibly improtant to have a creative outlet, for me it is photography, I bought a Panasonic Limix S5 with several lenses last spring, upgradibg ftom the Lumix GX80, and I get rid of a lot of stress by taking photos, and it is fun to show my coworkers my new photos and gear.
