Yes it's flexible. I think some people are set with their hours but my boss lets me choose.
Around a month. I was interviewed by a group of people. I expected to be interviewed by the Executive committee but no, there was The assistant, a co-worker, and an internship student, if we pass that filter then we get another interview with them again and finally with the Director.
The amount of work, They pretend you to perform the job of at least 3 departments and the environment is toxic, full of gossip. You can't trust anyone. The worst is the lack of Ethics they have.
