I recently interviewed for the Engineering Lead position at Octopus, and the entire process was a highly positive experience. From start to finish, the process took about 5 weeks, but I received support at each step.
Begins with a 30-minute chat, and then there was a discussion centred around leadership and team management principles. The next stage was a technical take-home task. Nothing too complicated, took about 3-4 hours.
After the task submission, I entered the System Design stage. This stage was somewhat T-shaped - and covered a broad range of topics with deeper dives into certain specific areas.
I also received feedback within a few days after each interview stage, which helped throughout the process. The overall atmosphere during the interview was positive and respectful, and I never felt pressured or undervalued. Everyone was extremely polite and professional.
