I don’t think it’s realistic to think that software engineers can pick up advanced statistical modeling on the job, unless they’re pairing with statisticians. There’s just too much background involved.
Your overall condescending attitude in this thread is really disgusting.
The "search practitioners" I'm referring to are pretty uniformly ML Engineers . They also work on feeds, recommendations, and adjacent Information Retrieval spaces. Both to generate L0 retrieval candidates and to do higher layers of reranking with learning to rank and other systems to whatever the system's goal is...
You can decide if you agree that most people are sufficiently statistically literate in that group of people. But some humility around statistics is probably far up there in what I personally interview for.
