Modern...ish Vocational Testing

Holla(nd) mundo!

The Holland Occupational Themes is a theory of personality focused on the vocational profile. It attempts to measure the affinity to six different categories of occupations. The six types yield the "RIASEC" acronym, by which the theory is popularly known in the field of career counseling.

We go through the following steps:

  • Loading of example data
  • Minimal exploration with pandas
  • Result dashboard with plotly

You can take the test online in: https://openpsychometrics.org/tests/RIASEC/

I'd like to refresh the comercial aspect of the data world for an interview. For this I gathered a list of Key Performance Indicators to use in practice problems, scrapping from a few websites using HTTP requests, Selenium, regular expressions and XPath.

In [9]:
kpis = {}
for category in categories:
    name = category.split('/')[-1]
    print(name)
    chrome.get(category)
    try:
        extra = chrome.find_element_by_xpath('//div[@id="featured-snippet"]/ul').text.split('\n')
    except:
        extra = []
    kpis[name] = list(set([e.text for e in chrome.find_elements_by_xpath('//h3[@class="strong h4"]')] + extra))

Con un poco de atención, podemos observar, del gráfico superior al inferior:

  • El vibrato de la flauta
  • El tono de la obra (C# ~554hz, Prélude à l'après-midi d'un faune)
  • La melodía
