Queries regarding role, team and expectations

Hi!

I came across many job postings at EY GDS for Digital Risk - Application Security role.

Could anybody please share some insight into how the team for this role would be?

One of my friend who applied and interviewed was told that they are hiring for a single client as of now.

Any thoughts what would be the expectations on a new joiner who is unfamiliar to working at consulting firms like EY for Security roles?

Any information is appreciated.

Thanks
