This happened a few years ago, so hopefully it's changed. I have just now been able to talk about my experience.
The worst interview I have had in my entire career, I was interviewed by two leads, neither bothered to get up to greet me when I walked in. One person yawned without covering their mouth as I was talking. Both incredibly rude, looking bored and going through the motions. Clearly, they didn't want to be there or had decided I was not worth their time. Their attitude reflected the general vibe as soon as I walked through the door - an overall malaise that was palpable.
As soon as I walked out of the interview room, they both burst out laughing. Extremely unprofessional behaviour from senior people, and not sure how they thought it was completely acceptable. Never experienced anything like it. Would not recommend working there to anyone except if everyone were fired and they started over.
