i was there a couple of weeks ago and they said they were interviewing until april 30th. they gave me a little over a weeks notice by email when they invited me so probably not done yet.
They are finishing on the 29th of April (a Thursday), they don't interview on Fridays. I interview on the 28th of April (had a choice between the 28th and 29th). Call them and ask if they are still inviting... they might.......
