It's again so strange with the hiring, I would say, I mean we were starting to notice it quite soon I mean that is an interesting thing that in a couple of weeks you start to feel either there is going to be a fit or something goes wrong. And that's exactly the case and again sometimes I'm questioning myself. Would it be possible somehow to avoid this situation, maybe we were having too few interviews? Maybe we would need some extra testing or whatever? But you know I was working in a big bank where costs were not an issue, and we're spending a lot of money on hiring mid-level managers, with all possible testing, etc, and I remember my manager was telling me that our success ratio is fifty-fifty, even with those tests, I mean basically when it concerns mid-level management which is a kind of complex position, it's not some technical skills, it's those interpersonal skills, etc. You hire a manager, it's a tricky thing. That success ratio is fifty-fifty with all the testings and all the possible things, so it just proves that it's even not a question of some particulate test, I mean sure, probably test, the more you will do, you'll do testing better probably. But it's good to have a certain number of crucial tests, but still, the complexity is there. And the other aspect is still interesting that despite that fact when you start to work with a person you will realize that fit quite soon. I mean you will realize that just when the person will start working, after a week or 2 you will have that feeling is it a fit or not, or is something going a little bit to bad direction. Or maybe it will be in a way that okay, a person is still okay, maybe the skill level is not that high as what we're expecting or what the impression was but the person is still okay so there might be different things but nothing is better than a few weeks of direct experience of working with a person.
