I had a worst interview experience with Bain Shanghai at Bain's Boston office. Before my interview, I received an official invitation through email from Bain Shanghai informing me that I was going to have 3 case interviews for my final-round. However, when I arrived at Bain's Boston office 5 mins ahead of time, I found out that I was going to have only 2 case interviews instead. No one informed me in advance about this change. What's more, my scheduled interview for that day was at 10:20. However, I had to wait for 50 mins at the reception and had my first interview at 11:10. No one came to find me until I asked the front desk why it took so long. The sequence of my interviewers also changed. In addition, I received a phone call Friday evening informing me about my interview results from one of my interviewers. And I received another phone call Saturday evening informing me again about my results from the same interviewer. Besides, the interviewer even got really inpatient when you made a mistake. I did have good experiences in my first-round with Bain. So this was totally unexpected. I regret I give up opportunities in the US and choose Bain Shanghai instead.
