During my summer internship with YouTube I was involved in doing research into the site-wide re-branding effort that eventually went live 12-months later at the end of Summer 2017. Due to signing an NDA, not all details of the project can be shown.
Mid-way through my internship I was approached by one of my mentors and recruited to conduct a highly sensitive internal intercept study. The purpose of the study was to get feedback on proposed major design changes to the YouTube site. The request for feedback came from upper management, in order to understand how the design decisions that had been made to that point would be received by users. Due to the sensitivity of the changes non-Googlers could not be considered for this researcher and instead a population of non-YouTube Googlers was chosen.
This study provided me with valuable insights into performing internal intercept studies effectively, as well as with conducting highly sensitive research with a large potential impact. It is very unusual for an intern to be trusted with research with both this level of potential impact and sensitivity (this research was internally confidential and I was not permitted to share details even with other YouTube employees - I can only share such details as this now as the re-design has gone live), which demonstrated the trust that was placed in me by my mentors, as well as their opinion of my competence. Although this research was commissioned in a short period of time, it was very effective in changing the course of certain design decisions in the re-branding effort, which had a lasting impact beyond my internship.
