Pros
I’ve worked for Slalom Build (the engineering branch of Slalom) at first as an intern and later as an engineer. The number one reason I decide to join full-time after the internship was the management. They have complete mastery of the agile development cycle, so the project went smoothly. Additionally, I felt like they trusted me to get my work done--I was never micro-managed or nitpicked for long lunches or short days. I get more PTO than I know what to do with and generally feel overly-rewarded for my performance. The hours are reasonably flexible and the environment is very inviting and casual.
Cons
My only complaint is probably more personal preference—I’d like a slightly more professional environment and to see more faces in the office before 9 o’clock. It’s pretty quiet in the morning. Additionally, because we’re located in the heart of the city, the commute can be a little rough.
