investigative job

A fire investigator is an investigative occupation that has secondary interests of realistic and conventional.

Investigative jobs are those that work with ideas, and require an extensive amount of thinking. These occupations can involve searching for facts and figuring out problems mentally.

Realistic occupations have work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery.

Many of the occupations require working outside and do not involve a lot of paperwork or working closely with others.

Conventional jobs follow set procedures and routines. These occupations can include working with data and details more than with ideas. Usually, there is a clear line of authority to follow.
