* Work is very dull, not interesting and filled with horrible corporate process and red tape. As a result, you won't be able to learn much as an engineer.
* Engineers in london are not given the same support as the Nottingham counterparts.
* Performance management is completely unfair. You are not rewarded on you're technical ability and delivery but on how well you sell yourself to senior managers.
* HR is very unhelpful, non responsive and their only interest is to protect the company.
* Hiring is also very biased as well. Again people who are all talk but no substance get hired while actual talented engineers are not taken into consideration. This results in many hires having imposter syndrome.
