I just interviewed last week and nothing has changed. IQ test is easy, just go for the first thing that comes to mind. Don't overthink them. IFR test is a couple of holds, vdp, dh, taf, landing mins from chart, apch lights from chart, required atc reports, frost formation, holding speeds, 123 rule, alternate mins, holding times.... nothing you can't find in the aim.
The interview is pretty basic as well. Tell me about a time when you... basic knowledge of the most recent aircraft flown, finger fly an approach, more mins questions, apch lighting, msa, why mesaba, how are you going to get through training. The gouge on aviationinterviews.com is very helpful.
Good luck
