What Level would this be compared as Passing one of the JLPT exams?
I mean how much studying would be required to reach this level?
I would assume it is fairly high degree of understanding.
I ask this because I will soon be working for IBM and I would like to transfer to Japan after a Year or so. And one of the requirements is to have a Business Level understanding of Speaking and writing Japanese.
It depends on what is your definition of "business Japanese"
If you just want to be able to function in Japanese society, have people take you seriously, and be able to hold your own when there are no other bilinguals present, you'll need JPLT level 2.
If you want to pass yourself off as being able to handle (nearly) any situation like a Japanese, possibly deal with business negotiations, or be able to successfully navigate the nuances of the language, you'll need JPLT level 1.
You probably need Level 1 to read a newspaper, or at least to make it a reasonable endeavor.
If you want to do translation or interpretation work, don't even think start thinking about it until you can ace the Level 1 exam.
I passed level 1 in 1997, but back then struggled to do some occasional translation work correctly. Now I'm a parttime professional freelance translator with a satisfied clientele.
See the website below for information about the skill level and estimated studying hours for each level of the exam. I would take those studying guidelines as the minimums. Also, every hour you spend simply interacting with someone should count as an hour or more towards study.
Oh, and whatever you do, learn as many Kanji as you possibly can. That's your key to a reasonable working vocabulary.
