I applied through a recruiter. I interviewed at Fuse Energy in June 2026
Interview
Met with recruiter discussing company.
Met with engineer to do a system design session for a running app.
Met with engineer for coding screen which was leetcode hard.
Overall seems like a typical startup, but I wouldn’t recommend bothering with an interview unless you can easily complete leetcode hard problems in <30 minutes. Overall not worth your time otherwise.
