The first interview was a call with my prospective manager. This was fairly informal and a good opportunity to learn about the job and the team.
There were then two interviews back-to-back: one technical and more process-oriented. This was fairly full-on both in terms of technical content and being on the spot for 2 hours straight.
The final interview I thought was a great idea, with someone unrelated to my team and with no expertise in my area, meaning that we could both focus on the wider fit and more general aspects of working at Dojo.
