Answer it, but too "practical" purposes like "it's one of the most fundamental demands to get a job" are dismissible(Of course it comes home to me that y'all HAVE TO SUFFER from the obsessive paranoia for the knowledge and command of English and the requirement to learn to speak it.)
I'm Japanese, and I'm totally impressed that though derived from such a "necessity", your linguistic skills are much more overwhelming than ours which is internationally notorious.

I feel it especially when the famous business TV drama, "未生", features a female intern who can fluently and facilely both English and Spanish.

Besides, out of the programme, I definitely understand what the exact labour market conditions in SK are like. For I specialise in Sociology and I study in a seminar whose professor is a Korean (who visited Japan more than 15 years ago and has since stayed here), and he indicates many times the status-quo of Korean social welfare-provision system and its economic basis, telling us that "even if you make tremendous effort to run as fast as possible to take a seat, when the number of chairs is too much limited, it might be just worthless and useless."

Anyway, if you have any merit or advantage other than this point, please tell me, and discuss it.
