- The author's initial perception of Bell Labs was that it couldn't be cool because their dad worked there, but they later appreciated the applied division's important, behind-the-scenes work.
- The One Year On Campus (OYOC) program allowed new Bell Labs employees to earn a master's degree on the company's dime while receiving 60% salary, with a requirement to graduate in one year.
- Key projects included designing a slide rule for salespeople to give on-site cost estimates for private branch exchange (PBX) systems using piecewise regression, which avoided delays.
- The inventory control project tackled wasteful personal stockpiling of circuit packs by technicians, implementing a system that reduced costs and improved accessibility.
- Bell Labs' structure included distinct research (Murray Hill) and applied (Holmdel) divisions, with the latter focusing on practical telephony problems and supporting operating companies.
- Management encouraged long-term careers, as illustrated by an executive persuading an employee to stay with promotion prospects, though attrition was high among younger OYOC hires.
- The interview reveals insights into Bell Labs' culture, including its focus on hiring from universities, rigorous employee assessments, and valuing advanced degrees.
- A notable anecdote involves a binocular vision test during the hiring process, highlighting the company's thorough vetting, even for roles not requiring precise depth perception.
- Experimental design is emphasized through examples like efficient weighing techniques and factorial experiments that uncover hidden interactions in industrial processes.
- The post concludes with a call for more information on OYOC from former participants or managers, especially those with degrees outside Operations Research.
