Yes, this is extremely Netflix. The "fix" for this is to mandate that they can no longer post an ad for engineers, but rather they have to post separate ads for each engineering role. Maybe this is better, maybe not. If a person applies to L4, are they allowed to be hired at L3 pay? Will that confuse people?

> For small companies and single openings

levels.fyi chooses not to publish some comp datapoints because there's too little data, which means publishing the data is tantamount to publishing an individual's compensation.

I hear you on the goal, but the details are tough.
