The London part of the crew (to be precise: only some of its reps) struggle to eradicate their overtly condescending thinking towards the other offices' people, without whom - which they seem to be constantly forgetting to realise - they would fall spectacularly come the first tough day.
The remuneration system is haphazard. As the time wears on, some of people whose work's quality was questionable are given pleasant, well-paid tenures for no apparent reason other than that they've just stayed for long enough.
On the other hand, it is nothing frown upon at Revolut to be promoted to a new role (having won a tough recruitment) only to see that one's been given an effectively smaller net salary, since the entry roles entail extra pay chances which are closed afterwards as one advances. Needless to say how it may play with one's motivation.
The feedback path is deficient when it comes to people perched a step higher up the ladder. It is factually impossible to have an influence against somebody over you in the hierarchy, should you see that person not living up to their duties.
There's a feeling of disregard to the level of stress a typical consumer-facing employee is exposed to each day. What is more, instead of soothing the impact, there comes a second, tough stress blow from the line managers focused on the KPIs. One may imagine that although stress is natural and can be beneficial, it can't be cranked up endlessly as straining it doesn't go on par with better results or higher discipline.
Lastly, an unpleasant surprise that one would rather avoid witnessing is the one whereby the in-house recruitment process sees some staffers outpowering the tough competition and being promoted to the new roles, for them only to be told on the eve of being introduced to the new position that their new contracts had been scrapped due to changing objectives. Regardless of the legitimacy of such turbulent decisions (which may be well justified and which I don't dispute) being tossed to and fro in such an aloof fashion is incredibly burdensome to the psyche. Such shockers undermine everybody's confidence and render many a crewmember dubious about the stability of their own jobs.
