Pros
- People at QS are very smart, personable and approachable people. I definitely feel that it is an environment where I can learn a tremendous amount from my colleagues - Good perks: Health Insurance, Work from Abroad (I am spending a month in an entirely different continent this year) , flexible hybrid working - Once a month there is a meeting where insights into company performance are provided and an AMA (ask me anything) with the CEO, providing a lot of transparency - The work tends to be very interesting and challenging - You are giving a lot of responsibility - I have a very healthy relationship with my line manager where I can be open and transparent with him and know that he has my best interests at heart. - There is a very large learning budget that you are encouraged to utilise (with no clawback agreement) which promotes self development. - People tend to develop in their careers quickly here.
Cons
It is a relatively small company so of course there is a trade off for all the freedom this allows you, and that tradeoff tends to be all the growth pains that smaller companies tend to experience: - There is a lot of change, sometimes too much, in terms of ways of working, team dynamics, culture etc. - There seems to be fairly high levels of attrition (though the cause of this is unknown) - Financial uncertainty due to being bootstrapped (though this is likely due to change with investment) These are all tradeoffs that you take when you work for a start up and personally they are worth it for the perks.

Business outlook
Pros
- Interesting projects focused on tackling complex business problems - The opportunity to work across multiple industries with opportunities to specialise if desired - Highly knowledgeable and supportive team - Unsual bi-annual appraisal cycle, increasing opportunities for promotion and pay increases
Cons
- Certain processes are messy but probably to be expected given the size of the organisation - Overall the working hours are good but if on a short client project there may be additional time required (nature of a consultancy)
