The worst interview I have ever had in my career. My on-site interview, I had scheduled 5 interviews with different people of the team. I met with the hiring manager for around 30 mins, it was just a casual tech interview. While I was waiting for my next interview in the room, I heard they were singing happy birthday to someone. Then, I met with a project manager for about 15 mins and she was so in a hurry that, she was watching her phone clock all the time. I asked her who has a birthday and it became that the VP who I had to meet to is the birthday boy and she said I'll not meet with him because you know .... After the second interview, I had to meet with another guy who unfortunately all of the sudden became that is on vacation in London. How is possible to schedule on-site interview a week before that and you don't know who is in the office? After 5 min someone came and said they're canceling the interview and will follow up by email. I lost half of the day to meet with them and they cancel the interview in the middle of it. That was the most unprofessional interview that I have ever had. -hr phone call - hiring manager phone call - on-site interview
