Nice co-workers. Easy place to work. Flexibility in your time spent working. Allowed to work from home. Extended my single semester co-op into a double block.
What I wish was different
A lot of work would be done on one or two days of the week and then you wouldn't have much the rest of the week.
Ask for more work otherwise you'll just be bored most of the day. Leave the office like an hour after everyone else to avoid traffic, they'll probably let you leave work early on Friday to make up for it so you don't work over 40 hours.
