The InstantSearch team at Algolia organized a hack day to tackle several big projects simultaneously, despite being a small team. To prepare for the event, they brainstormed ideas and chose one to focus on, ensuring everyone was familiar with the project before starting. They found a suitable location outside the office to minimize distractions and maximize focus. The team divided into smaller groups, with some members working on junior-friendly projects, focusing on pair-programming and knowledge sharing. The event included coding time, followed by non-coding team-building activities like an escape game and sharing a meal. The hack day resulted in several innovative projects, including accelerated mobile pages, React InstantSearch-compatible apps, and voice-controlled search interfaces for YouTube videos.
