2. What EY-Parthenon are looking for


EY-Parthenon look for more personality traits than any other strategy consulting firm we have looked at with 10 in total:

Accountable – In the EY-Parthenon strategy practice junior consultants rapidly assume a level of responsibility on their projects. This means that the consultants need to be comfortable with taking accountability for their work when working with senior colleagues and clients.


Adaptable – Strategy consultants work across industries and work on unique problems that do not have an off-the-shelf solution. That means that consultants need to adapt to industries, niches and problems in order to deliver high quality solutions for their clients.


Agile - The way that strategy consulting projects are structured means they are fast-paced and constantly changing. Teams that are agile and can flex as priorities change are the most efficient.


Analytical - Client projects typically include an element of data analysis and the datasets are often fragmented and incomplete. EY-Parthenon expect their consultants to be able to able to conduct analysis quickly and competently.


Curious - Each project is different in strategy consulting and requires new research to develop the understanding of the project team. Consultants that are naturally curious learn quickly and are motivated to understand new concepts which is hugely beneficial to the project team.


In the know - Interestingly EY-Parthenon place an emphasis on consultants being up to date with current affairs. It benefits their ability to understand the client’s current challenges.


Numbers savvy - With analysis being a common element of strategy consulting projects being numbers savvy is a non-negotiable for EY-Parthenon. Calculations and analysis often needs to be performed at pace.


Resilience - The fast-pace and ever changing nature of strategy consulting projects means that completed work is often discarded and good work is often morphed by seniors. Resilience and self-belief is required to continually produce work when reward can sometimes be infrequent.


Strong communication - The concept of upward as well as downward communication is promoted at EY-Parthenon. Communicating workload, estimated delivery times and when you need further support is imperative to project momentum. Communication is the key to producing high quality work at pace.


Team player - All consultants are expected to be good team players as each project will have different team members and there is little time to build rapport and relationships. Good team players can hit the ground running and work effectively in any team.
