Pros: There is a lot of work with a lot of variety. At this company, if you don't define your scope of work, others will by continually asking you to take on more responsibility. Which is great, if you're ambitious, capable, and love to take on responsibility! Overall, the work is great.
Cons: Time off policy is too good! This is great on a personal level, if you need or want to take time off. However, on a project level, this definitely impacts who will be available and when. More time off per person means we need more persons, so maybe that's actually a good thing for job seekers...
