ColoRight interview questions

I meet at first with the algorithm team leader. The interview involved at first some explanation about the company; then i was asked to describe my thesis, i was given a few minutes to write down a description of what it was about and went over it with the interviewer; in the last part i was asked to answer two questions involving developing some basic algorithm, the first being knowing two clusters and a point in space finding which of the clusters is closer to the point and the second was to develop the least square method. I was told that the next step in interview process will involve meeting with the head of R&D so he will ask some questions.
