There were 3 interviews. The first was a general introduction and question answer session like a typical job interview. The second was your presentation on what you think you will be doing and ultimately how you be a good fit and survive in the industry. The third and final interview was introducing you to your mentor and ultimately that person deciding if they like you and going more in depth on the compensation structure of the firm and any questions to be answered. Then they shake your hand and you get the job. The whole time they are weeding people out of the interview processes because it is highly competitive.
