I was most surprised by how much we’re able to accomplish within the time frames and resource constraints all businesses face.

What are Mizuho's culture and people like?
Mizuho's culture is a blend of feeling like a small firm while scaling and growing quickly. Through all of the change and growth, Mizuho has kept its sense of familiarity and togetherness, which is something I truly value.

My work email.

How is Mizuho different from other places you've worked?
Mizuho allows you to work on projects in all different areas. It also takes care of employees through upward movement or other benefits, such as learning and development opportunities.
