Welcome to the community.
I have a good story for you here. Not my first job, not even close, but a good first day story.
I showed up at the reception desk on my start date, as instructed in the e-mail. They had no idea who I was. Nobody informed them I was coming. They had to call around to find someone in HR to come get me. My new boss was not in. They forgot to tell him they hired me and set a start date. So I’m sitting with HR and they give me the usual pile of paperwork that you have to fill out when you start. The only problem is, they sent that all over e-mail to me, and I had already filled it out.
So now we have the problem that HR doesn’t know what to do with me as I’m now at the office, they have nothing else for me to do, and they have nobody to hand me off to. Fortunately I knew people that worked in the department I was starting in. I sent them a message and they came down to get me.
The person in the dept who basically oversaw access to everything was out for 2 weeks. They would also have been the person that gave me the walk through of, here’s our setup, here is where everything is, etc. So for the first 2 weeks I really don’t have access to much. I get lots of e-mail alerts for tickets and I’m sitting there going, okay I know how to fix that but am I supposed to fix that or is that the service desk, or one of the other infrastructure people. It’s a VMware issue? Great, I don’t know where vCenter is hosted or the access URL. Those types of problems.
A week later I’m at a datacenter with a coworker, and he says can you look at this, and I said sure what’s the portal link? “They didn’t give you that?” No. Where do I find the creds for that? “They didn’t give you access to the password vault?” Dude, they gave me nothing. I got dropped in a desk and left to fend for myself. I’ve been crawling through the network for the last week on my own and have a good feel for where a lot of important things are, but no access to them. He got me set up on quite a few things which made life easier.
It was an interesting 2 weeks starting until I finally got hooked up with appropriate access to things and a list of portals and assets etc.
I survived and thrived there. Moral of the story, just hang in there. Life is going to drop unexpected twists and challenges at you, even 20+ years into your career. Take a breath, define the problem, and then get to work on solving it. Don’t be afraid to ask questions or for help.
