Pros
I have been with Lightspeed for a year and a half now and I can say that most managers and colleagues are a stella bunch. Their new offices at 4 Millbank must be in competition with Google with a huge breakout area, tons of informal meeting areas, no shortage of boardrooms and private meeting rooms, games room and even a quiet room that's decked out with sofas, bean bags and hanging chairs...and let's not forget the coffee. Great coffee.
Cons
People tend to stay in the same roles for ages and only receive significant promotions when they've been with the company a better part of a decade and management have been placed on the back-foot with no choice but to look inward. Seems it's easier to hire out and train for the vacant position rather than to promote and be left needing to backfill the position as well as ensuring that the promotee is up to the task. So if you're super competent and expect to see your work rewarded with greater responsibility don't expect to be considered for progression...you're too valuable where you are now ;). Unless you sell your soul to the devil and practice office politics...then you're set for the big time.
