I would approach with a great deal of caution....something a bit smelly. Certainly unprofessional.
Jobs for this start up were hawked around a couple of months ago by a Jersey based recruitment company I had never previousley heard of then Xenon got hold a few weeks ago.
I know several individuals who were type rated and ticked all the right boxes but never so much as an acknowledgment.............and surprise surprise the jobs have disapeared from the agencies.
