The non-surprising aspect here is the set of skills needed between postdocs and those in the private sectors:
Differences by type of position can be readily inferred from the previous figures. Postdocs were far more likely than PhDs in the private sector to regularly do basic research and utilize advanced physics principles regularly in their work. A large proportion of PhDs in the private sector were regularly involved in design and development, applied research, and quality control.A lot of data also on the job satisfaction, and whether they had sufficient mentoring from their advisors.
These differences reflect inherent differences in these types of employment; postdocs are temporary positions with research agendas largely motivated by scientific exploration, while jobs in the private sector typically involve producing a tangible product for a customer or providing a service to a client.
