The first interview with the CTO went well and was quite positive. The second interview involved an algorithm writing task, which was surprising but went well.

After a two-week silence, the recruiter contacted me, explaining they had forgotten to follow up. I was then given a coding exercise to submit. It was not easy, but interesting and took a few hours of work. I never heard back about it; there was no feedback.

Subsequently, there was a full day of on-site interviews. A junior developer asked me to write an algorithm on a whiteboard. This was the first time I encountered such a request for an SRE/DevOps interview. The code didn't even relate to Ops or Systems work, and again, no mention or feedback was given regarding the home exercise, which was more Ops/System related.

Other interviews went pretty well.

I eventually received a no-reply email late on a Saturday night, with no explanation.

I believe they should be more upfront about the level of developer skills and experience they expect for an SRE, and provide a little more feedback after six interviews.
