Pros
Everyone I worked with was young and of a similar age - because they prey on inexperienced job seekers who are less likely to stand up to their bullying behavior
Cons
I experienced a very toxic work environment where multiple people were bullied and harassed. Their idea is to constantly hire new staff, demote and/or neglect current staff, provide poor training and resources, expect consultancy level work but provide entry-level pay, all to create an environment based on mutual distrust and anxiety. Avoid working here if you can. Terracycle invests a lot into marketing and PR for their big-name brand partners, but very little into actually doing anything good for the planet. A total scam. Also, they get very defensive over the slightest whiff of a criticism. See their PR responses to the reviews on here - that tells you everything you need to know about this s**t show.
