I think the obstacle is communication because each person is difference culture, difference language, difference background so it hard to understand for each person, but if we work together we have to adjust it together we just need to be able to understand the individuals' differences and see cross cultures. In a multicultural team, good teamwork and willingness to understand the other person is important When your colleagues speak different languages, it is very easy to misunderstand each other. Pronunciations can cause confusion and people may feel uncomfortable asking someone to repeat themselves, especially when the situation is stressful. Working with colleagues from other countries and cultures can at times be challenging, but it is so rewarding when you can learn from each other and open your eyes to other ways of life.
