Comparison


It is so challenge for me to accept the truth. The interviewee is SDE II with two years experience. He did share his experience to work on books cracking coding interview and also elements of programming.

The interviewee works on preparation of so many interviews. It is true that they all get so many experience on interviews. The companies are Amazon, Facebook, Tik Tot, Square, Box.
