From my experiences with different populations, and acquaintance with a fair amount of past research, it is clear to me that differences among individuals within any particular ethnic or racial group are much greater than differences between cultural groups as a whole, especially with respect to job-related abilities, including interpersonal skills. Individuals bring different levels of ability and experience to the job, both of which affect the development of their competence, knowledge, and performance in a particular position. Although members of a cultural group do tend to share some similarities among themselves and some differences from other groups, people are largely idiosyncratic critters. At times we perceive and respond to the same situations differently from other people of either our own or other backgrounds. We have individual differences in ability and personality that are independent of cultural background.
Personality is affected by and in turn affects each person's experiences and abilities.
Because ability and work experience levels vary more from person to person than from cultural group to group, no generalized cultural guidelines or management prescriptions can possibly be valid across the range of individuals of any ethnicity. As humans, we tend to categorize both things and other people, and it's often necessary and functional to do so.

Demographic statistics are blunt tools, however, and these do not reflect that, despite their common national origin, workers who come from Mexico are ethnically and individually diverse.
