Octopus Energy Backend Engineer interview questions

Attended their event, 1st round technical interview, did practical task, 2nd round tech interview. Offered another tech test for a lower level position. Rejected but got good feedback in a 1-to-1 call with the API team head.

Interview process was reasonably long but very relaxed. It consisted of four video/voice calls plus a technical challenge. At each stage clear guidance was given on what to expect next. It was good to chat with multiple team members and get a feel for their goals and values.
