Pros
You can wear what you want free internet (totally over priced and as soon as I left, I switched to a better, cheaper competitor) come and go as you feel like it (well, if you are a manager) free car parking
Cons
I joined Zen thinking it was part of the "it" crowd. How very wrong I was. My manager was wet behind the ears and clearly didn't have any other experience of working life outside of Zen (as of most managers). If your face (or in the case of the credit and billing manager - your mouth) fits, then sit back and enjoy a cushy life. If your face doesn't fit, then you will be dumped on from a great height, made to believe you are worthless and will end up feeling physically sick with dread having to report into work every day. The expenses policy is a joke - woe betide you buying chocolate sprinkles on your hot chocolate - purchase ledger and payroll will ring you, scream and shout at you and remove the extra 20p or so from your expenses claim (chocolate is a luxury - the fact that you have been staring at tarmac for 300 miles, trying to keep the penny pinchers in a job is swept aside). You will also have to explain why your journey of an additional 4 miles resulted in an extra £1 increased expenses claim even though (in my case) you just landed a corporate deal that keeps the food in the fridge of these small minded people. As for promotion, forget it. You will be passed over for external candidates. Zen are not a people company. They are out of their depth and as soon as I could get out, I did. Steer clear. Biggest mistake of my life.
