Snapchat's new milestone What exactly do product managers do? According to Tobi Lufadeju, product managers are walking encyclopedias. At Reliance HMO, she’s a product manager who is in charge of their consumer business unit. New to the role, she battled with impostor syndrome at first. “The first two months on the job were not easy. I joined an existing team which meant that I had to do a lot of learning and observation in the beginning. My team members would throw around in-house language during meetings and I also had to figure out how to speak the engineering team’s language. I dealt with impostor syndrome big time.”
