Pros

There is nothing positive about mars, this is not the right company for you! Stay away as there are many other companies in Slough

Cons

Be warned. Mars has a very peculiar culture that allows management to bully their staff. You are expected to work overtime without any additional pay. Projects are never finished as priorities are changed on a daily basis. You will then get the blame in your annual review. Only those that are friends with the management team get promoted. Young people do not stay in that company, most leave within 2 years or so. I would never recommend this company and urge anyone to stay away. It’s simply to worth the stress. You will be undervalued, over worked and pressured. I’ve seen grown adult men cry due to the overloaded pressures of the job. The smart ones leave and this is my intention.

Pros

I’ve been at Mars (Yorkville site) for about three months as a Quality Systems Senior Specialist, and so far it’s been a great experience. Everyone has been genuinely friendly, welcoming, and willing to help. The culture feels very supportive—people want to see you succeed and are quick to share knowledge and offer guidance. My manager has been amazing and is truly invested in my growth. She’s helped set clear expectations, encouraged development, and provided the tools and support I need to be successful.

Cons

None so far—still new, but my experience has been very positive.
