Pros
It's a growing company with a lot of ambitions and a constant staff shortage so you will definitely be exposed to more environments, projects and challenges than you would in the average job so you will learn a lot. Unlimited holiday which you are encouraged to take (although you will be expected to be available whilst on holiday and expected to rearrange if a deadline or important date comes up during your holiday) The actual concept is very exciting and a fun product to work on
Cons
No job security - even when your employee feedback is strong. Many employees have had their jobs hired out from underneath them whilst being told that their job is safe and that they're doing well. Often employees have found out their job is at risk when they see their own jobs advertised, when no performance concerns have been raised. The culture is "this isn't the right environment for everyone" which is a fairly uncontroversial statement for a start up, but this statement is then used as a blanket excuse for why employees haven't worked out. There is never any self reflection when long standing or even new employees quit suddenly citing the culture as toxic, or when staff are suddenly let go with no due process (ie performance meetings or improvement plans). In under 4 months over 15 employees from the head office team quit or were let go - bearing in mind the size of the head office team at this time, this was about 33% of the team. There is a concerning lack of ethnic diversity in head office, and although the gender split is fairly equal there is a significantly higher turnover rate of female staff especially at a senior level. There is an assumed incompetence and worse, malicious intent, about almost every employee if a mistake is made. Whilst mistakes are outwardly encouraged, the reality is if an employee does make a mistake they are 'marked' as incompetent or as an active saboteur of the company whose sole intention is to bring the company down from within. The CEO is incredibly paranoid, which he wears as a badge of honor, and is unable to regulate his emotions which means it is often like working in an office with, and for a company run by, a volatile two year old. Unfortunately he is also very passionate about culture and ensuring everyone has a clear view of what culture looks like within that company. These two things combined means that the culture he creates is also paranoid and volatile with priorities and targets that change daily based on his latest business development whim and/or his personal feeling on any individual (and therefore their team/department) within the business.
