Tell me about some of the most difficult problems you worked on and how you solved them.

Frame yourself as resourceful, with a propensity to think fast on your feet. Demonstrate that you aren't easily discouraged. Where there is a will, there is a way, which is the attitude you want to convey. Meeting deadlines, overperforming, learning, and innovating is the aim of the messaging in your example. You want your answer to exhibit determination.

"I was part of a team responsible for building the different bots for a platform. We divided our team into three sections. Two for monitoring and security, two for flagging spam, and two for testing our security. Somehow, things got off track with the team. First off, the patchwork we were implementing resulted in a spaghetti algorithm, and the problems escalated. Secondly, the project turned into a not-so-friendly competition to see who could out-perform each other's work, hurting the group's productivity, and losing sight of the intention of the project. It also created some strain and friction between certain individuals on the team. I pointed this out and influenced everyone to work together on developing each set of bots in stages. I encouraged each member of the team to rotate working side by side together. This way, everyone got to work closely with everyone on an individual level, spotting each other's work. This diverse collaboration fostered our teamwork mentality, and created a situation where we over-performed as a group, turning our project around."
