So so much.
For starters, so many reviews speak of a boys club mentality, that you would be frowned upon if you left on time, and as true as they are(or were in some cases, some things have changed for the better), the biggest problem is a select few individuals who created a spineless management, who's attitude towards the company exists just to accept paycheck-to-paycheck.
The leadership are there just to accept their paycheck with no real care about what each product is doing. This is evident in the way that they deal with product managers, and that relays down to team members. Micromanaging them and not letting the product manager make the pragmatic decisions needed, without listening to the team either.
You'll find conversations that circle 4-5 times, going through stages of being a confirmed decision, progress has started, and the goals change 3-4 times within the span of several days, all without "data" and based on pointless questions that are asked just to prove a specific point. 2 weeks later, they'll ask why it's not done, then forget that they were the ones who said to put things on hold until a decision was made to push through.
Key members of staff who have been there for years, will be gone overnight with no answers except "we just had to let them go". Confidence in keeping your job is low if you ask too many questions. That's why there's a strong belief of a "boys club".
Don't expect a promotion or pay rise anytime soon either. You'll find better rates elsewhere, but do expect to learn a truckload while you're at Freelancer. Just know where to draw the line of sacrifice to learn, and know that you can learn anywhere.
