Pros
Meet amazing people, work for multiple campaigns, good for those who thrive on diversity, spark passion in others, feel a global sense of unity, learn about amazing cultures and witness emerging ecosystems face to face, you can tailor your role to your unique passions by selective partnering. Get experience relevant to almost any future role - many former employees have gone on to amazing careers and roles.
Kontras
The burnout can be real, some companies have a whole team whose annual role is hosting 1-2 hackathons and extending the impact of the innovations created, even those teams feel a burnout. Running 10+ hackathons per person per year can suck your energy like nothing else. Anyone working here needs to take rejuvenation and boundaries seriously or you may end up retreating from society / becoming a monk / having a breakdown. The pay is also below market so you must be passionate about the organizational goals.
