Met with Hiring Recruiter.

Interviewed with the lead architect who was clearly not a software engineer, but more of a DevOps engineer. He interviewed me as if I were applying for a DevOps role.

The questions didn't apply to an ML Engineer at all. One question was a vocabulary test and didn't align with industry common terms.

System design had nothing to do with a real-world scenario.

The code question was a difficult medium on LeetCode.

In my opinion, they are trying to be something they are not. To get through the interview process, one would need to study just like for a FAANG interview, with a focus on DevOps. Except, if one was going to prepare that hard, wouldn't they go work at a FAANG company?

Seems unrealistic to me, but power to them for trying to be elite.

Design a system that mines logs for billions of emails that didn't go out when the issue was sporadic.
