Aside from work, the people I worked with were great.

Cons

Well where can I start. I had two offers and unfortunately I chose this as I was basically sold a dream on how this is the best company to work for and I will learn and develop a lot within my field of civil engineering. After starting I soon realised within the first week I made a pretty bad decision. Developement - well none existent. I came in as a graduate civil engineer however I was given tasks that seemed as if I was a gradaute administrator. Whether that be ordering materials or office supplies, I was pretty much the guy for that. Within the first 3 months, I learnt 0 engineering and everything admin / ordering. Also tasks other employees couldn't be arsed to do, I sort of had to do those as well and if not completed I would get shouted at like as if I was meant to be doing it anyways, I spent my first 3 months sat in the office and rarely got to go out even though my job is to be out on site most of the time learning. Line manager wasn't no help either, most emails were left unread in their inbox. Management also do not care for your concerns and if you are leaving don't even bother asking you whats the reason and if they could do anything help. It's as if the world can end but as long as the project gets completed they are happy. Benefits - none at all. Not even car allowance. The other gradaute had their public transport paid for and other employees that were employed had their car paid for yet I had to fork out for my own car and expected to use time to time to carry these little tasks on site. When asked if I could receive one, I was told a lie and how my project is my base location and not the main office in Bishops Court even though my contract stated that. Working within this company made my contemplate at one time whether I picked the right industry to go into, however, luckily I was able to escape and find a reputable and better company that helped restore that motivation within me.
