2450 TT, 1100 PIC, IP/EP and I am sitting on two CJOs with another interview next month. You should be able to get interviews.
I felt Checked and Set (app review) was worth the $300 and I started getting calls after fixing the things Charlie recommended. Emerald Coast was probably worth the $500 if for nothing more than interview confidence and helping me keep my foot out of my mouth. RST I have not gotten my $$$s worth yet but I also haven't been contacted by Delta or FedEx yet either so it hasn't been a priority.
One of the CJOs I'm sitting on is from Frontier; I took that interview completely cold, before doing ANY prep, and didn't even really google the gouge first. They were my "safety school" airline, the worst-case, nobody else calls job. My friend there put in a rec but also strongly dissuaded me from seriously pursuing them because of the management toxicity they have now. It felt good to see what a cog test looked like, experience an LOI, get raked over the coals in a panel interview and get the job offer, definitely good practice for the other airlines and at least a safety net in my pocket.
