Java Developer

First Data was bought by some Americans, the corona came, they are getting rid of people or putting them on unpaid leave. The candidate got unpaid leave for 4 weeks, he has an order until the end of June, then it can be extended. He doesn't like the project that much, he thinks it is slow and is thinking of not signing. He has a contract with an agency where he has 3 months notice, which has a contract with some company that is a contractor to First Data. First Data is supposed to let him know no later than 45 days before the end of the order if he will be renewing (which is mid-May). In addition, he thinks there is a very reputable person working at the agency, so he doesn't think they would keep him there contractually for 3 months if he wanted to leave, but he will address that when CSOB is interested. He also said that he wanted to be on the project until the autumn and then go abroad for a longer period of time, but the corona prevented him from doing that for at least a year, so it is to be expected that he might want to leave next year.
