I applied online. I interviewed at MongoDB (New York, NY) in May 2017
Interview
The recruiters were knowledgeable and involved in candidate experience. The first two rounds were phone interviews. The final round was a series of four onsite interviews. The six interviewers were engineers across four different teams. The interviews were typically structured. The interviewer first asks about background/resume, then asks a technical question, and finally accept any questions from the candidate. Coding is done on a shared editor or whiteboard.
