Akemi Hamano, a recruiting consultant at *Hays, says that, with the exception of blue-collar positions, companies are looking for a business level of Japanese ability sufficient for frequent back-and-forth communication and being able to make ( 1 ) together. David Price, client services director at *Robert Half, is more *succinct. "In most cases it's pretty simple - if your co-workers and/or clients can't or won't speak your language, then you must speak (and often read and type) ( 2 )," Price says. At the same time, whereas ( 3 ) for conversational level abilities are high, Alan Adkins, president of *The Refined Group, notes that there is more flexibility when it comes to reading and writing, due to an awareness that learning kanji is hard. The value placed on Japanese ability may not be only related to ease of ( 4 ) top communication. "Many companies also look at business level Japanese ability as a sign of ( 5 ) to Japan as well as solid work ethic as most Japanese people seem to understand how difficult their native language is,” says Anthony Blick, a senior consultant at *PowerUp Solutions. 注) Hays 会社の名前 Robert Half:会社の名前 succinct : 簡潔な The Refined Group : 企業グループの名前 PowerUp Solutions: 会社の名前 ( 1 ) 7. decisions X (2) 7. mine (3) 7. exceptions Y (4) 7. academic X (5) 7. command 7. illustrations 1. yours 1. expectations 1. business 1. commitment . quarrels 7. ours goog . experiences . daily . compassion pre prior 200 I. subscriptions I. theirs I. experiments I. professional I. competition
