Nothing strange. All Qsense.
They are just trying to see how many new potential slaves there are out there, so they can adjust the terms and conditions (aka blood and sweat squeezing) accordingly.
They also fired most of the HR that got rid of us in the first place (karma), most likely including the entire flight crew recruitment team. Type rated or not, as with anything in QR they plan a maximum of 2 weeks ahead with data of 8 months ago so it wouldn't surprise me if after you finish the ground courses suddenly you'll be transferred to a different fleet (and indeed with a bond), starting all over again.
