They did some interviews last week and there are some people on this forum that interviewed so if you do some research you can probably get some info from them. From internal stuff, it is the same format as last time we hired. The sim is tough so make sure you get some time prior to the interview.
There are 2 classes planned in December. December 1 with 9 and December 20th with 12 and classes every month following that based on the large amount of attrition that they are planning.
