Some interview prep services had the gouge so dialed in that candidates were responding to scenarios in the line ops portion with identical reactions. For example, during the line ops drill, they give you a small whiteboard and dry erase marker so you can make notes just before and during the exercise. Many candidates were setting up the whiteboards in identical fashion.
Canned reactions to scenarios removes the “who are you really?” factor, hence they don’t want you to prep.
My view is, get help in delivering your responses to interview questions. Learning how to format and deliver a story without fumbling all over is important!
Get help in formatting your resume.
The bottom line is that SWA wants to see “the real you.” If you come off as pre-programmed and insincere, it won’t go well.
