  • Great if Network isn’t your primary role

    I just want to say your podcast has been a great review of all the networking stuff I’ve learnt on-the-fly over the years, but is now being pulled into context (episode by episode). I highly recommend this podcast to others who have done networking (even for years), but don’t have any formal networking training. Great work. I love that Holly fearlessly asks the questions I’d be hesitant to ask. Great work.
