Welcoming culture with strong focus on development and AI

Pros

The company is full of ambitious, experienced people, with many long-serving employees. This creates a welcoming environment and makes it easy to integrate into the culture. There is a genuinely inclusive and friendly culture, supported by good equipment, modern facilities and access to useful tools such as Gemini and Claude. There is a strong focus on becoming AI native, with encouragement to explore and adopt new ways of working. Active guilds, team lunches and innovation days help build connections across the business, and new ideas are encouraged, even if they can sometimes be difficult to put into practice. Employee happiness is treated as a genuine measure of success, which is refreshing to see. Dedicated training time is provided every two weeks, demonstrating a commitment to learning and development, even if workloads do not always make full use of it possible. The benefits package is strong, including a generous holiday allowance, a season ticket loan, eye test support, Spill wellbeing services, a good pension scheme and Zoosh benefits. The company values are more than just words. They genuinely reflect the behaviours and qualities that are recognised and rewarded across the organisation.

Cons

The recruitment process is thorough but quite lengthy and requires a significant time commitment. Every interview was positive and well run, but candidates should be prepared to invest a lot of time in the process. There is a strong emphasis on personal development and continuous learning. However, it can be difficult to find enough time during the working week to make meaningful progress. At times, there can be a lack of clear strategic direction, with teams understandably focused on responding to immediate priorities rather than shaping the longer-term future of the productand business. Heads are turned too quickly with whats hot right now, rather than what will sustain customer loyalty. There is a high ratio of leadership and oversight compared with hands-on delivery, which can sometimes create unnecessary layers of coordination. There are a large number of meetings, and some overlap in purpose. Reducing duplication could help create more time for focused work. The role involves a considerable amount of administrative work, both from an HR perspective and in people management. This includes activities such as AI readiness, knowledge sharing and compliance, which can add to an already busy workload. There are several different types of objectives to manage, including organisational, team, annual and personal development goals. Dedicating more time and focus to achieving these would make them feel more meaningful. Documentation is comprehensive, but information can be difficult to locate. Improving organisation and discoverability would make it easier for people to find what they need. The culture is highly autonomous and suits people who are proactive, intentional and comfortable making things happen independently. Those who prefer more direction or a quieter working style may find it more challenging, as success often depends on actively contributing, collaborating and making your voice heard. The mandatory office days feel somewhat inconsistent with the company's asynchronous, hybrid approach. While face-to-face collaboration is valuable, some roles benefit from quiet, distraction-free environments for focused work, and a blanket policy does not always take those differences into account

Pros

On the positive side, there is some flexibility in working arrangements, and a welcoming, positive office environment in Lisbon. Overall, this company can work well as a stepping stone if you are early in your career and want to learn quickly.

Cons

A significant amount of time is spent on goal setting, performance tracking, and repeated documentation. The process feels heavy with limited visible connection to outcomes or improvement. In practice, compensation and recognition do not appear consistently aligned with the evaluation processes across employees, which creates a sense of disconnect between effort, assessment, and reward. There are also noticeable differences in how teams and offices are treated. Some departments feel clearly more valued than others, which affects overall fairness and morale. At the end of my employment, I had to escalate a legally required payment after initial refusals from HR (People Services), despite the obligation being clear under applicable law. It was only after escalation that it was resolved. This created a strong impression of poor professionalism and lack of accountability.
