Process started off extremely well. Prompt follow up and scheduling of interviews. 1. Had ~30 minute HR screening call 2. Had 3+ hours of on-site second round interviews 3. Had 3+ hours of onsite final round interviews Took ~2 weeks for a follow up and received a simple rejection email. Asked for feedback and was told there was none. Not a single bit of feedback for ~7 hours of interviews? That is outrageously unprofessional and rude. I gave you almost an entire workday of my time, the least you can do it respect it.
