Ummm... High School Sophomore?

Caffeine.

BSEE. Contract Programmer. I work out of my house.
My recent hobbies have been 3D modeling and game programming.

I am a School Support Officer Level 2, and I work for three different places (public, and somewhat under funded country schools.) on network administration.
Usually though, I end up fixing vandalism, training staff and students how to use app #XYZ, and finding just how old a PC I have that will run winXP with all our server/monitoring/antivirus overhead.
Depending on the time of year, I'm either flat out the whole week, or spend most of the day trawling the web. End of term 1 right now, lots of politics, so I stay in my office and hide.

College student; probably going to major in Biology with a concentration in Neuroscience.

I have a BA in music with a concentration in composition. I work as a cataloger in the music cataloging section of an academic library. I'm not a librarian, but my supervisor is. It is a much more production-oriented job than one might imagine, but at least I am able to put my university degree to use.

About to graduate from college in Aerospace and Ocean Engineering, hopefully I snag a job related with planes or ships, ships are a lot of fun, and planes are just cool.

I'm a quality inspector (I'm not sure if it is the right name, because I don't know the name of my job in english. If I'm wrong, someone please correct me) in one german company producing electronic components.

what kind of qualifications are needed for a professional translator in your country?

I'm a student, did a certificate 4 & diploma in IT at a tech college and am doing a degree in IT with a minor in (slightly different areas of) IT at uni, the degree also included the Cisco Certified Network Admin certificate.
Also I had a spare subject so I'm doing dramatic script writing, the fact I'm enjoying that more than the IT worries me slightly, I'm hoping that its because its a refreshing change from the regular IT stuff I'm doing and for the fairly high number of cute girls in the class, up to and including the lecturer.

IT-tech support trainee at a high school. Here, PEBKAC only begins to explain the problem...

I am geodesist, and my hobby is to do anything else than my job.

what kind of qualifications are needed for a professional translator in your country?
Same as in most countries I expect. Which, unfortunately, is none. As long as you can prove you are compentent in the language to a high degree you'll be considered a lot better than most. Now, if you want to handle certain "official" documents you will need to be accredited by certain organisations -- and again, usually ability will trump qualifications -- unless they are looking to rip you off with a course to get their own "qualifications".

My father used to be a translator, and he hated. Even though it payed well, he could go for long periods of time without a job and he would start worrying whether something would come up or not. He says that it simply used to be too stressful, so he decided to go teach at a university instead.
