Pros
decent pay & perks good w/l balance good product, market leader, almost no competitors great place to relax and retire (if you don't give a damn and can smile&swallow) :-)
Cons
huge tech debt. poor management & communication (starting from VP level). Ad-hoc decisions & projects & timelines & priority changes, bad planning, lack of clear vision & strategy & roadmap. Quick, poorly designed and unverified solutions that "seem to work perfectly fine, we'll see how to improve it later (no)" are painful to support/change/replace later on. No cross-team communication. Processes, policies, guidelines, playbooks and documentation generally either do not exist or in a poor & outdated state (mostly for compliance). Toxic environment: technical proficiency & experience is not valued, managers like to dictate and create vision of work "here and now" instead of trying to do something right. Being a nice guy loyal to the management simply doing what you are told to do without questioning and reasoning is the (only) key to success (including career opportunities). Performance review process is funny (at best) and obfuscated - someone's unverified and unsound verbal 'feedback' can simply ruin your hard work and you won't be able to find any roots - neither HR nor senior management will help you. This is all relevant to IT, but things are much better in DEV/SWE.
