Although of 1500 Zappos' employees, I doubt many are getting frequent offers or recruiters reaching out. How many are doing IT, development or high level sales

Although of 1500 Zappos' employees, I doubt many are getting frequent offers or recruiters reaching out. How many are doing IT, development or high level sales stuff where well paid jobs are plentiful? I imagine the majority are customer support agents of one kind or another, packers, logistics people, etc.
