Real, anonymous reports from people who interviewed for Financial Analyst at William Blair, newest first and distilled into what to expect across the loop.
My interview journey started with what I expected to be a balanced mix—half behavioral and half technical—but it turned into almost entirely behavioral. In that first 30-minute conversation, I went through the standard story questions like “tell me about yourself,” why the firm, why investment banking, and why my industry group, plus a few more behavioral prompts about how I’d led and worked with people.
After an initial HR screen, my process moved into multiple rounds of interviews at their office, and it felt fairly structured. I ended up with a case study round and then followed that with more interviews, with most of the conversation taking place in person.
