The interview process at Canonical was one of the most extensive I've encountered. It included a written assessment ( about 38 questions), cognitive and personality tests, three early-stage interviews, a talent/HR interview, three final-stage interviews (including a timed presentation and panel exercise), and a final executive conversation. The process stretched across nearly three months, often with long periods of waiting between steps. While many of the individuals I spoke with were kind and insightful, the lack of communication between stages and the absence of any personalised feedback at the end was disappointing—especially after investing so much time and preparation. After eight hour-long interviews and multiple assessments, I received a rejection email over a week after the final round, with no explanation or guidance.
