Pros
Good starting salary for young single people who have few overheads. Most of the time is spent away from home in purple hotels eating cheap terrible food and getting fat, but at least you get that on expenses. A lot of time for yourself sat in hospital corridors and empty laboratories watching an invisible vapour fill a room. Plenty of time to look for better jobs and question why you applied for it in the first place. After working a couple of 10+ hour days each week you are rewarded by sitting in the office completing really important paperwork from 6 years ago that hasn't been completed because the engineers that did the deployment has come to their senses and subsequently left the company. If you work hard for bioquell straight for 3 years and complete all the development they set for you then you will get a 2k raise, 5 more years and you may get another. 11 years and some brown nosing management and you may get a van to work from home.
Cons
Unsociable working hours, be prepared to work from 8:30 to 22:30 then the next day on site for 6:30 for another 10+ hour day. Mandatory weekend working ruins all attempts at a social life, but it's ok because you can book a weekday off to spend with your mates, while they are at work. Unpaid overtime means the advertised £9.75 an hour for a 38.5 hour working week is more like a £7.50 an hour 90 hour working week. You actually get paid more stacking shelves at Tesco, which is disgusting considering bioquell charge up to £2000 a day for the service you provide. The management don't care about your quality of life or mental health, just your ability to get the job done for the client.
