Unity

• Most of the co-workers are nice and highly skilled.
• Compensation is OK.
• Nice benefits.
• The tech stack is interesting.
• Massive scale of data.

• No career progression if your work is not classified as "high impact." Meaning people with good connections will work on new and fancy projects, and the rest will be left with all the maintenance work on legacy systems.

• Lack of documentation practices. Two-year-old Slack threads and source code are the best documentation you can find.

• Understaffed teams.

• Constant addition of middle-management layers.

• Most of the middle managers don't add much value.

• All the decision-makers are in the US.

• Almost no options other than ads-specific roles in Helsinki.

Think more about the roles of a team lead / manager. Limit the work in progress per team member. Sometimes less is more. Re-orgs and team changes have little affect if none of the underlying issues are addressed.
