The most bizarre part about the John Deere interview is after all those derogatory remarks, they emailed me a week later asking me to fly to headquarters for another round of interviews. Despite having no offers, I turned down the interview. Was pretty upset about the way the interviewer had treated me.
I would have asked why that was. Do they lock employees in a room alone, and force them to solve problems without help or any outside interest? If not, then GPA is not relevant. If so, I will be shorting your stock.
Having good grades across the board is great, but not having interest or success in the narrowly tested and unrelated subject is just silly.
The main metrics that matter when evaluating someone is how they are now and how fast they progress(ed).
