Investment Bank Summer Analyst Interview (Positive Experience; Average Interview)
I applied through an employee referral and the process took a day - interviewed at William Blair in January 2014.
Interview Details – Very welcoming group. They flew me out from Philadelphia all expenses paid. Met 8 people who all took time to talk with me while doing an seemingly informal interview. Everybody was nice and the work environment seemed very appealing. Some logic questions were thrown in as well as technical and fit. Overall great place and great people.
Interview Question – Tell me the value of this telephone as if it was a company and explain your reasoning. Answer Question
Investment Banking Summer Analyst Interview (Positive Experience; Average Interview)
I applied through college or university and the process took 2 weeks - interviewed at William Blair in February 2012.
Interview Details – Initial contact was made with on campus recruiting. They selected me for an on-campus interview. This initial interview consisted of equal parts fit and technical questions.
The next step was a Super Day at their office in Chicago. This consisted of 8 back to back interviews with bankers ranging from Analyst up to Directors. Some of these interviews were all technical, some were all fit, and some were mixed.
I found out I got the offer the next day.
