One of the biggest challenger banks in the United Kingdom is Monzo. The startup founded in 2015 employes a lot of people in the UK and is quite transparent about the career paths and responsibilities of every job position. Executive Support is quite a popular job in the world and no one has been as transparent as Monzo how they support growth for this kind of profession.
Can actively communicate on what they are working on and are seeking feedback by other people to improve their work.
Can work independently on smaller tasks and deliver results but also looks to optimize existing processes, procedures and even products.
Works closely with people above their level and consults them when working with tasks for the first time. Executive Support employees need guidance, approval to ship projects of a certain impact and support by more senior folks to strive in the professional environment.
Eager to learn what they need to do in their career but executive support employees should have enough knowledge to make a decision based on information. Learning (for example Monzo's tools: GSuite, Slack, Lattice, Peakon, Notion, JIRA) should be balanced to delivering value.
