I've had 2 different awesome experiences with this firm. In one case, I received significant interview preparation and career coaching, and was successfully placed in a role in the finance community.
In the second instance, I had a Hay's staff who wrote up a short couple of paragraphs about my profile and sent it around to a surprisingly wonderful list of firms. He put a lot of effort into his advertisement of me and it was great to see someone go the extra mile.
I'd recommend this firm to any high quality candidate in finance. Only apply here if you are a good person who gets along in a team, this firm has standards about who they will represent and they will do extensive background checks on you.
