Pros
The car park is free. You can get training but have to justify it and ask.
Cons
Once you get in the door, you will discover that you need to interview for any project work. The promotion process also involves a promotion panel. Getting a promotion however is not necessarily a reason to celebrate as they will likely use it as an opportunity to get you to sign new terms and conditions. Pay is very, very bad for technical staff. They don't seem to recognise that as an IT company they need people good at IT. Instead they focus on business people. As for pay-rises, they seem to think that they can shoe-horn people into a normalisation curve which makes any pay-rise a lottery. You could get recommended for promotion but marked as "needs development" for your annual review. Of course even getting "exceeds all performance" will not guarantee a pay increase. You are still at the mercy of the stats. Finally they have imposed a sickness absence policy that ignores significant health issues. You have only 20 days budget to be ill no matter what the cause. If you break a bone and take 15 days off, you only have 5 days for colds for the rest of the year. Exceed that and you will lose pay. Staff are leaving in droves right now so there is a significant brain drain, including people who have been there 10 or more years.
