Interview process was straightforward. I had worked with a Senior Engineering Leader who was already at Prosper so I did not have a Phone Interview. The recruiter called me to understand more about me, and gave me a lot of information about Prosper and got me excited. I gave them availability for onsite interviews and it was scheduled within the same day. For the onsite interview, I was sent the list of interview panel beforehand. It had a set of Senior Engineers and a Senior Engineering Leader and the Recruiter who had talked to me over the phone. The technical interviews were challenging. It had questions on programming knowledge and Algorithms and Data Structures. There was a Design exercise involving Service oriented architectures too which was a lot of fun. Interviewers were friendly and knowledge-able and it was intense but fun. Loved the office vibe. The energy was palpable. The interview with the Engineering Leader was about my background, projects I liked working on, and answering questions on Prosper culture and frank exchange on the challenges on culture.
