Pros
I worked at Nectar off and on for years, first as a full-time employee, and then as a contractor. I certainly wouldn't say that the work was easy -- it's a communications agency, which can mean long hours, weird hours, and client service conundrums. That said, I thoroughly enjoyed every employee that I worked with (and certainly wouldn't have lasted for as long as I did as a contractor if that wasn't the case!), and I appreciated that I honed some incredible skills that I still rely on as I continue my career.
Cons
As I said before, it's a communications agency. I worked some weird hours, BUT I do appreciate that they gave the weird hour projects to me as it enabled me to do more in my contract work.
