Good work environment, friendly. Good policies for returning interns and job applicants.
What I wish was different
More hands-on work. People were very poor at communicating.
Advice
Be clear about the types of work/group you wish to work with. It will greatly improve where you are placed and the experience you have.
The hiring manager is very poor at organizing, did not properly outprocess me from the internship for a full year, you have to double check everything. Even your own paperwork.
