Pros
Talented people - you'll definitely have a chance to improve your technical skills. All the analysts here are very skilful compared to employees of other companies.
Proactive environment - Apart from BAU tasks, you are encouraged to find new ideas and experiment them.
Agile Working - that's not very common for Data Analytics due to the high number of ad-hoc requests but this is very well managed here.
Cons
You might need to spend extra time on things like showcasing your work, be a 'champion' of a subject/tool etc., or working on subjects that are not in your area/responsibility. Although these things might sound like a pro, sometimes they might become quite distractive and result in overloading in terms of workload.
