Has anyoneo interviewed with Keystone Strategy before and willing to share their experiences ?
Not me but someone I know did.
Firstly they had a screening round over the phone which was focused on competency/FIT questions.
For the final round, they had 3-4 interviews, all of which had a 20-30 minute case.
Keystone is focused on digital/tech sectors, so the cases will all be related to this space. In this particular person's case, all the questions were Digital market entry cases.
Hope this helps!
