I had two interviews. Each one lasted about an hour and a half. They seemed friendly and very professional. Also, they seemed to be very honest and gave me the right feeling after each interview. It seems like a good place to work.

In the first interview, they asked me about an image with Gaussian noise with large variance. They asked how we could make some segmentation. A recommendation for you: go over the basics, such as how to calculate variance, what the variance of two iid variables is, how to handle Gaussian noise, and how to find edges, etc.

In the second interview, I felt that the interviewer came up with questions according to my background.
