I'll start worrying after 3 months...
It's the risk we all take when we choose this kind of life. In the end you have to be good enough. So far I've been good enough. Although so many flooding the market so quickly has led to a demand for qualifications and I've never bothered with them. If you can't Do it there is no point in having a qualification to say you can. That's my motto.
I just need all those newly dumped to wash out of the system. ING is being rather slow in their responses, they want someone who has worked in their bizarre transition to Agile and I've been there and done that. Makes me stand out from the rest but, still, you're in a competition.
