The point is that for whatever level of fizz-buzzing they feel they need to - far too often these companies can't fizz-buzz themselves when it comes to basic interview hygiene. You know, like maybe reading the candidate's resume and cover letter (or talking to the recruiter to whom it was explained "I haven't worked with language X at all, is that OK?") before asking them to code over the phone for language X, for example.

Or even post a job req that accurately reflects the true needs of the position in the first place. Or (getting back to the subject of this thread) when giving take-homes, provide reasonable instructions as to what is expected and by when (and under some reasonable time frame), etc -- see for example this chestnut, posted just now:

A two-way street, and a bit of common sense. That's all I'm asking for.
