I applied online. The process took 1+ week. I interviewed at PerceptiMed in Jan 2016
Interview
2 rounds - 1 involved programming test and 1 was all about computer vision-machine learning. Both the rounds were over Skype and lasted for 1hr approx. The programming round was about algorithms and complexities. The computer vision round was about image descriptors, their pros and cons, image processing and machine learning techniques. My experiences with them and a 25 min presentation about the work I did through my career.
