<human>: Some background- I just started my first fulltime job. The way this company's computer department works is you interview you and if they hire you, they decide which team to put you on after they clear you. (As opposed to applying for a DB Admin position or Web Developer position specifically.)

My resume includes various mobile apps, usability studies, and interactive technology. In a placement meeting, I spoke with a member of the mobile team who seemed to like me enough to 
give me his contact info. I was pretty happy but didn't hear anything about my placement after that. 

When I walked in my first day, I expected to be somewhere on that mobile team. ("They were the only team 
I spoke with so where else would I go?" is what I thought.) Instead they put me on a database project. 

While I did study basic database stuff and worked a little with some on my internships, it was not something I took interest 
in or looked into further. I don't know what it was that screamed database on my resume and in my interviews, but I'm afraid it's so out of my comfort zone and skill set that I'll do a bad job. I just got sucked into a lease and have school loans to pay 
off, so quitting is not an option for me. 

I feel self-conscious talking to my manager and mentor about it because a) they don't know anything about me and my resume (and have told me as such) and b) apparently I'm replacing 
someone who left in a hurry and they "really need me to fill in for him," so I feel guilty for even having these thoughts.

I also have reason to believe I was already placed on this team even before my placement meeting (completely defeating the purpose of the meeting imo.)

Summarize the given text in a few sentences.
<bot>: New job, placed on team I don't know much about and don't think I'm suited for, afraid I'll do poorly, current team
