For what it’s worth, I was hired end of last year and on property currently here. Just my take based on my experience during the hiring process: the whole person concept is big ie what value do you bring beyond flying skills as United seems to be emphasizing a lot of corporate employment aspects for United Next rather than more traditional interviews.
I did my own research on prep and didn’t pay a company. Presented my self as the “hero of my own story”. I had 10 various stories based on my professional and personal experiences and used those to answer questions. I also incorporated CRM/TEM principles into my answers demonstrating additional skills I bring to the table. I didn’t even bother trying to wrote memorize questions. For the tech, just was professional, showed up prepared, and when asked if I was doing it as a Fo or Ca I said CA of course (coming from a ACMI FO job).
Used the same prep/interview technique for multiple airlines and got CJO’s from UAL, DL, and SWA. Not saying prep CO’s aren’t good, just chose to use my own research as I was already at a pretty good widebody intl gig.
My background going into interview: Mil warrant officer RTP, regional CA with 6600TT, 2700FW, 1100TPC, widebody ACMI FO with 75/76 type, no degree.
