I got this phone interview opportunity through networking. This initial phone screen only takes 16 minutes, but it covers a lot. Firstly, I was asked to walk though my resume. Secondly, I was asked why do I choose private equity firm. Thirdly, I was asked a few technical questions, which you can see in the most difficult question part. Fourthly, I was asked where I am originally from and whether I mind moving to Philadelphia. Fifthly, I was asked what I like doing when I am not at school. Finally, I am allowed to ask any question.
