Don't be fooled. They say they won't test you on AVL trees and RED Black trees, but they will ask you to code some puzzle. They will say they aren't looking for a correct solution, but they are. You MUST solve this to get the job. Unfortunately, the I met with a few of the team members after my technical interview, and you could hear the disgust in that man's voice. Everything about this company is a visceral and complete lie. They say they are passionate about helping people, but they don't know how their device functions, how the AIC works, or how to detect blood flow rate if the pump is malfunctioning (Doppler). If you are too smart, they will decline you. The entire tech team here is asian / white, so yet another sham. YOU HAVE BEEN WARNED!!
