Pros
The best reasons to work at Freelancer are all gone. The best and the smartest have left.
Cons
The technology stack is unmaintainable. Poor architectural vision has resulted in a "distributed monolith". If you take a role here, you will not work on new or interesting technical problems. Instead you will merely inherit projects which have a huge knowledge gap as everyone that ever worked on them has now left. Your career path or goals are unimportant. Do not expect regular reviews. On the up side, hang around and eventually your superiors will quit or be fired, which may result in a "promotion". Salary is well below market/industry rates. If you're currently working at Freelancer, shop around you can easily get a 20-30% pay bump elsewhere.
