It was all day process. Several smaller interviews that were 30 minutes to an hour, an hour presentation, and technical panel. Started at 8 AM and ended at 2:30 PM

Day long interview, tight schedule, met many scientists in various departments. This was good experience. I was asked about past works, what idea I could bring in, intelligent, in depth questions but good experience during interview. I arrived night before and left next day late evening. The interview started early from 9 in the morning and lasted till 5:30 in afternoon. During this process I was asked questions or interviewed by fourteen different people including HR.
