Write an essay, rewrite your CV, meet me in person, do a coding test before I...

Here is an example of a coding test for a current (albeit permie) vacancy that I came across recently.

Is this sort of thing becoming more common now then?

Apart from two references agents also like to ask for one of more of:
1. Writing an essay why are you the best candidate for this role
2. Rewrite your CV for certain spec
3. Meet them me in person for a chat
4. Do a coding test
... before they send CV to a client.
While this proves the existence of the advertised role, is this usually a good investment of time?
Do you do normally agree to do anything of the above?

1. Not really, I have highlighted a few points, but not an essay.
2. Nope, I work in a smallish area and my CV is totally geared towards that.
3. I will do this after I've got the contract to sign papers and be bought lunch. Did it once as a newbie about 9 years ago and have turned down any requests since.
4. I expect I'd say no, but depends on the role.
