      Pros

      - Nice non-management colleagues - occasionally interesting work

      Cons

      The level of toxicity in this organisation is immeasurable. First jobbers/recent graduates are primarily targeted as new hires as they have no experience of what good company culture should be. Those with more experience or levels of seniority are quickly silenced, and skills or business process improvements are shockingly ignored. The CEO brainwashes employees, including some notable members of the SLT, into implementing a strong micro-management culture. Flexible working is not a possibility, and when you’re mandated to be in the office you’re not able to speak to one another if the CEO is also in. Any time spent talking is watched eagle eyed, which makes any form of collaboration impossible. QS uses generic terminology such as scale-up or organisational changes to justify rapid staff turnover rates. Simply put, if anyone wants to question or challenge a decision they are shown the door. The CEO is a cruel, narcissistic and manipulative individual who will patronise, gaslight and try to force you into a perspective which could be viewed as Stockholm syndrome. Yes the work can be interesting, and you can upskill fast (because of the resource problem and unachievable workload), but leave before you’re forced out - which for most colleagues is under a year.

      Thank you for sharing your feedback about your experience at QuantSpark. We are sorry to hear that you've had such a negative impression of the company culture and leadership. We take these concerns very seriously and appreciate you taking the time to provide this detailed feedback. We are troubled to hear your characterisation of the leadership team, and CEO as "cruel, narcissistic and manipulative." This is certainly not the culture or values we are striving to cultivate at QuantSpark. On the contrary, we have worked hard to foster a collaborative, transparent, and feedback-driven environment where all colleagues regardless of seniority, are encouraged to share their ideas and work together to drive continuous improvement. We have specifically implemented benefits, policies and practices to promote ownership, autonomy, and open communication. Our recent shift to a hybrid work model, with a requirement to work two days per week from the office, is designed to enable greater collaboration and team building, not to enforce micromanagement. Team members at all levels are regularly invited to provide input on business decisions, and we actively celebrate those who identify process improvements or innovative solutions. You're right that we do have some junior talent on the team, we firmly believe in nurturing and developing the next generation of leaders. At the same time, we've also brought on more experienced hires to help guide that process. Our goal is to create an environment where everyone, regardless of seniority, feels heard and empowered to contribute. We are going through an important transition as we work to professionalise and scale the organisation, and we know that can be challenging for some who have experienced a significant shift from the more informal culture that comes with being a smaller team. For those who embrace this transition, there are excellent opportunities for career progression, great benefits, and a supportive team environment. Thank you again for your feedback. It's only by hearing diverse perspectives that we can continue to evolve and become the kind of organisation we aspire to be.

      Pros

      There are a lot of emotive reviews on here, and while I can understand why people feel how they do, I think it is unfair to lump all problems onto the management/leadership team. I, for one, had a good manager/department lead who did their best to support in what was a difficult working environment for all involved. There are some people in the company who truly care about others and want to do good work, sadly most of these have felt no choice other than to now leave. I worked on some interesting projects where I was given a good level of ownership to develop my skills and ultimately move on to somewhere better suited.

      Cons

      It is amazing how much a company can change in such a short period of time. When I joined QS there was a buzz about the company and some exciting and interesting projects. In the past year almost all people with significant skills or experience have left meaning a chaotic and unsupportive work environment.

      Pros

      Quantspark has one overwhelming advantage, and that is, as noted by other reviews, its people. During my whole tenure the hiring was nothing short of exceptional and you will be working with a very talented and motivated bunch (keeping hold of them seems to present more of a challenge, but more on that later). The colleagues were a big part of what made working here so fun. If you want to get a lot of experience quickly, this is absolutely the place. You will work on a wide array of projects with a high degree of autonomy. This is an excellent way to learn. You will be encouraged to try new technology and experiment with new things, especially those with an AI flavour. These are material benefits that you would be hard pressed to get elsewhere. You will need to be comfortable with going outside the typical boundaries of your role and as such you will experience a very wide variety of project and sector. This advantage cannot be overstated and is critical to the value proposition of working at QuantSpark.

      Cons

      For me, the biggest drawback was remuneration. If you are early in your career or transitioning into a new role the wages are fair, however once you attain more seniority a clear gulf emerges between QuantSpark and the wider market. Projects are often accepted with 'ambitious' timelines. This leads to stress and prevents engineers having the breathing room to build truly great products. The company pivots too frequently. Communication from upper management can occasionally feel impulsive, making it hard to settle into a long term direction.
