Simple HR chat, then had an interview with the manager of the role. Was a brilliant conversation, a good overview of my technical background, and a simple technical test which I passed well. I smashed it out the park honestly.
Then I got feedback that they were looking for someone with much more experience / seniority. I have about 2 years, it seems they were looking for 10+years... So I don't know why I was sent forward with the process.
