I went to the first "group" type interview and it was cool. You go into the building and they give you a plac with "believe" or whatever word was on the one you were given, and you go into a room with a hiring person and they ask group questions, watch a video, and then do a worksheet.
They are really quick at getting back to you, I got a responce that same day for my 2nd interview. The 2nd interview is one-on-one with the hiring person for the department that you applied for. Its just like any other interview.
A couple days later they sent me an email (they respond to you through email to set up all of your interviews so always check it!) with a job offer (position,salary, ect). For this you have to log into your account, set up your appointment and fill out your new hire paperwork online.
From there I will let you know! My "on boarding" meeting is on monday so i will update.
