What features of Mexico's business culture is Joanna having difficulties dealing with?

Joanna's difficulties with Mexico's business culture:

• Language barrier: Her knowledge of Spanish is not as good as she thought, making conversations difficult.
• Social customs: She finds it hard to have conversations in Spanish, even when invited to colleagues' homes. She has to rely on her hosts to do most of the talking.
• Business practices: She is unfamiliar with the early morning business breakfasts and the long business lunches where business is only discussed at the end.
• Interpersonal interactions: She feels her Mexican colleagues are watching her and trying to decide if they like her, indicating a possible feeling of being judged or under scrutiny.
• Communication style: Mexicans tend to dislike much eye contact, which might be perceived as impolite, and they have a different sense of personal space, often standing very close and touching.

Answer: Joanna is having difficulties with the language barrier, unfamiliar social and business customs, and different communication styles regarding eye contact and personal space.
