Pros

Very friendly office environment. Lucky enough to get a nice supervisor who was extremely flexible with my hours and gave me time off when I needed it even though I was just an intern.

Cons

Eerily quiet office but it is to be expected of an engineering firm I suppose.

Business Outlook

Pros

Great people, great projects, lots of opportunity if you have that sales zeal and desire to make the company money.

Cons

For focused scientist and engineers that don't have a quarterly mentality, keep your six months emergency savings up to date, you'll probably need it sooner or later.
