My resume was sent in via recruiter. It took about a month to hear anything and then it went fast. Got a call on Tuesday for an interview on Friday. Was told to expect 1-3 people and an hour. It ended up being 3 1:1 talks, 1 2:1 talk, and 1 5:1 talk that ended up being 3 hours. I'm in good shape and could keep up with the fast walk and stairs and keep the layout of the building in mind. I imagine this was part of their assessment The energy with the first person was so high and got me so excited that I found it difficult to come down from there for the rest of the time. It threw me off enough that I didn't sell myself as well as I would have liked. Everyone was very knowledgeable and fabulous and I could see myself working with them. I had never experienced such an interview. I was completely wiped at the end of it.
