How did my first day at work go?

Everyone made fun of me at work, bruh!! Why am I that unlikeable? God, nobody ever bothered to call me during colleague outings. Why, God, am I that unworthy?
Wait! Wait! Wait, I didn't introduce myself! Right so I (Hirugao) had not had any job up until now. Don't you think it is funny? Then how I have survived up until now is a mystery to myself, haha!! Anyway, as a Japanese citizen, if you are not working, you'll be considered trash!! "Goodness, as life is a risky business in Japan. You're not supposed to be unemployed; otherwise, you'll find yourself hanging in a TRIANGULAR war facing “Earthquakes and Tsunamis." Likewise, in my case, unemployment is the third and most brutal key that made my life miserable, yet I re-energized myself and rekindled my hopes.

Here I got the job!!
As a penniless guy, I am unable to step out of my house often. Therefore, I have to manage to get the job this week; otherwise, my desire to visit Beijing’s renowned seven UNESCO sites, especially the Forbidden City, will always remain a pipe dream. If it's not enough, I'll be a homeless beggar in the future too, and I can't afford that.
On the very sixth day, after a demanding week filled with numerous intense in-and-out interviews, I received a call from NISSAN and guess what? Just hearing her 5 melodic words, "CONGRATULATIONS YOU GOT THE JOB" had me completely frozen. That moment brought a lot of tears to my eyes. Even the receptionist understood the situation and comforted me for a minute, but it was really a Joyce moment for me. I not only got the job but also got the opportunity to work with such a prestigious company. That made me all excited.

First day, first impression:

I put on the most elegant clothes I had for the event, and like a baby, all I could think about was stealing the show as soon as I went in.
The big day is almost here! Oh God, I don't know why I'm sweating so much. Hirugao, you can do it.
I said hello to everyone and went into the manager's office.
Salutations, sir. Hiruago, right, please take these files, review all of the stocks from the previous year, and provide me with a clear, succinct report in an hour (he didn't even get a good look at me!). I'll do it, sir. All right. Go. A lot of work needs to be done. Move quickly.
I didn't know where to start with this, so I approached my seniors for guidance. To my amazement, no one even bothered to listen to me. After their cold behavior, the first day completely ruined my mood. Now what? What must be done to get their attention, as it seems as though I am totally invisible to them?
It killed all of my enthusiasm for my first day on the job, so what should I do, in your opinion,to get their attention and become their favorite coworker?
