I'll assume monotonic, but is it even linear?

A Google recruiter has asked me to rate my Python skill on a ten-point scale. Can anyone calibrate this scale for me? At the moment, all I know is that ten is the better end, and since Google employs Guido van Rossum I don't want to overestimate. What's a three? a five? a seven? or is this some sneaky test of second-order knowledge and how I deal with bizarrely underspecified problems?
The goal is really only to be appropriate for the job but not a target for a vengeful interviewer.

Hihi. Google employee here.
The scale should have been explained to you, but here's a simplistic breakdown from memory.
10 - Guido will give you your next interview. Don't answer this.
9 - Core python developer or teach python at advanced levels.
8 - Wrote books on python, teach python.
7 - Very advanced programmer using python. Written large systems with it.
Write back to your recruiter and ask for a guide as to what numbers mean what if you want. It's all treated as relative anyway, you'll be interviewed on whatever you say your strengths are.

Response by poster: jerub, let me clarify that I'm a new grad, most of my "work experience" (one summer internship) has been in OCaml, most of my programming coursework (OS, networks, etc.) has been in C, and most of my Python experience is in fairly specialized contexts: Numpy and Cython because I'm a biochem major, ASTs because I had an internship building an embedded domain-specific language on top of Python.
So, could you continue your scale down to the 2-4 range? (or, better yet, is this scale documented anywhere?)

I would probably answer by referencing the programmer competency matrix in some way. I don't know that that's what Google would want, but at least it gives you somewhere to start.

Um. okay. So I don't remember the bottom end of it, and as I said, it's all relative, you're not going to be compared to other people; you will be interviewed on your technical strengths on the things that you rated higher than others. The scores you give at this stage aren't used except by the recruiters to discern who they will get to interview you in the next stages.
Definitely tell your recruiter you've got OCaml experience if that's where your core programming competency is. With any luck they'll give you an OCaml programming question or two.
As a rough guide, this feels right, but I'm really no expert:
5- Would be able to write software without a book.
4- Occasionally reference book to write a program from scratch.
3- Occasionally reference book to maintain a program.
2- Know basic concepts, can do simple things, but anything complicated requires the book.
1- No knowledge

Response by poster: Thanks for the quick reply, jerub! That helps a lot.
Incidentally, though,
"you will be interviewed on your technical strengths on the things that you rated higher than others"
I was only asked to rate my Python skill---should I have been asked to rate other areas?

I expect that part of what he wants to know is whether you can answer questions without getting flustered, and whether you're able to assess your own skill level. Also, unless he's expecting *just* a number it can't hurt to say "You guys employ Guido! He wrote Python! And lots of the world's best Python programmers work there. So in Google terms I think I'm a 6 at best - but anywhere else I'd be comfortable calling myself a 7".

Scribble the most advance Python you know for returning the number 7 in the box.
