So I thought first round interview would generally be very competency based with maybe some technical stuff. I guess those guys think I am competent enough so decided to grill the s*** out of me. 35 mins technical interview with no "break". I answered some questions pretty well but others not so well. I did manage to answer everything.
Now I am wondering if I can ever be prepared well enough for technical interviews. I have no problems explaining dcf, M&A models etc but not sure how well i can handle other questions such as how would you project sales if the client were to be taken over by a PE firm (I didn't prepare for it some didnt answer very well).
Do I have to absolutely nail every technical question to be considered a job at BB? :( or cultural fit is more important?
