FWIW, I did a M&G on 1/5, got the hogan test exactly 2 weeks later, interview invite 2 days after the hogan. The M&G was very laid back. I had no idea what to expect, so I wore a suit and I’d recommend the same for everyone else. Treat it like the real interview, however it was just a big conversation about myself and why United. It was actually a GREAT experience. The CP told me he had been doing a few per day and always waited until Fridays to send the list of names to recruiting, as to not bombard them with a million separate emails.
