TK Elevator Electrical Engineer Product Development interview questions

Very unprofessional, HR late to greet in lobby, no agenda, very us versus you. No response to follow-up thank you emails or phone message 2 weeks later requesting an update. I met with the hiring authority for one position and his senior, but another position was discussed in detail and that hiring authority was not present. Wasn't so much an interview as a conversation. Just very unprofessional. If they do approach me with an offer I would not consider it. The people I spoke to outside of the interview who work there mostly hate it. When the economy turns they are going to lose a lot of good people.
