I interviewed in August and have an Oct class date. The gouge was spot on and I don't have much to add that hasn't already been said.
1. Arrive early and get to know the group you are interviewing with. Everyone has some tidbit that was helpful such as inside info, interview strategy, a copy of the Jepp plate you somehow left on the printer at home. Your goal is to see some of them again in class.
2. Do your research about the company, ask questions during the morning meet and great, show you are sincerely interested in PSA.
3. Theres no reason to fail the written test. 90% you should already know, the rest is readily availible online. Don't blow that off, we had guys fail and go home.
4. Sim was MD-80. Basic profile but its a "jet" so its moving 3x as fast as your 172 set up. Think ahead as it will take a few moments for the sim to spool down and start to even consider getting slow.
5. Relax. Think before you answer the panels questions. Be professional but not uptight.
As an aside, remember that for every pilot on a msg board complaining there are another 50 who are enjoying their job and making it work.
