def scrape_job_details
   web_page = browser.current_response
   job_list = web_page.css('td#resultsCol')
   job_list.css('div.jobsearch-SerpJobCard').each do |char_element|
      
       title = char_element.css('h2 a')[0].attributes["title"].value.gsub(/\n/, "")
       company = description = char_element.css('span.company').text.gsub(/\n/, "")
       salary = char_element.css('div.salarySnippet').text.gsub(/\n/, "")
 
       job_details = [title, company, salary]
 
       @@jobs << job_details if !@@jobs.include?(job_details)
   end
 end

In the end, call the scrape_job_details method inside the parse method and write the @@jobs array to a CSV file. 

def parse(response, url:, data: {})
       scrape_job_details
 
       CSV.open('jobData.csv', "w") do |csv|
           @@jobs.each { |element| csv.puts(element) }
       end
 
       @@jobs
end
