Having worked with a number of PhDs who are seasoned workers in industry, I found them to be actually very humble and great to work with. What was great was just by working with them, could learn so much, stood out as inspiring people, often only finding out they had a PhD once you got to know them, they wouldnt be telling people they was 'Dr', just getting on with the work and it showed thru their excellence.
Thank you so much. I am currently a Ph.D. student and face the same issues with myself. What are your suggestions for improvement, especially with slow decision-making?
