I know quite a few pilots who are on probabtion, or the initial period of 8 months, while I recognise that this is often a time of significant personal expense, and not just type rating but for some yonger starters it is the massive cost of overall pilot training, it is great to get a start, and get their flying career going on. easyJet is a big company and a good one to have experience with.
If the candidate is flexible there are opportunities. I know one guy who starter in UK and took up permanent position in France and all through the first 8 months he was quite confident that he would get full time position.
There is strong regulation on pilot flying hours, and given that easyJet work within these, coupled with level of training and qualification that the pilots have when they start, I would have no safety concerns whatsoever.
Not taking from the feeling/sentiments that you have expressed 737Jock.
