작성한 답변인데 문법좀 봐주세요.. I agree that the tasks at international companies are more difficult than the tasks at local businesses. Because There are many differences of culture. In the case of my friend, he worked in the international company. He often has communication problem. Also, He has always jet lag when he participate in video conference with other country. As a result, some business were not finished well.
