Well quite interesting actually, TA contacted in January finding my profile interesting, then I applied through their website, no public position open for the period, at least I don't remember seeing it. I was contacted by manager, and went through 2 interviews, they collected information and never came back. Instead a public position was opened just a few days ago. Don't want to jump into any conclusions, but very hard to say that I have positive experience. Several times I was promised that they would return in few weeks time, and they never did.
