Candidatura
Ho presentato la mia candidatura online. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Mujin (Tokyo) nel mese di set 2023
Colloquio
I applied online. The first round interview with a HR is very comfortable. The HR is very friendly and professional. However the followed technique interview was totally a nightmare. The conncetion was unstable and the interviewer talked in a echoing room without headphones. Moreover, the tech leader has a little accent and spoke quickly. So it's hard for me to get what he said. He asked me to write answers on a paper and show it in front of my camera. It's very ridiculous. Actually we could collabrate on MT whiteborad. They have a strong bias towards learning based methods. So I think they show underline "No Deep Learning!" in the jd.
Domande di colloquio [1]
Domanda 1
the camera model; classical computer vision problem like corners and edges detection. Projective transformations
No DL questions. They want to solve with traditional algos. Interviewers aren't punctual, coming in late. And this was for first stage. The recruiter seemed nice though. Good luck guys!

Colloquio
There were three rounds. HR -> Technical -> Meet with CTO. The HR round that was fairly straightforward. It was mostly about understanding salary expectations and if any visa sponsorship is required. The second round was a technical round with the Director of the Computer Vision Team. Here the questions were related to the fundamentals of Geometric Computer Vision. Questions related to Essential, Fundamental, and Homography matrices, Camera Intrinsics, etc. Importantly, there were no questions on Machine Learning based Computer Vision. While the Director clarified that they are happy to use ML based methods, I did not feel like it was a priority for them. They are similar to other traditional robotics integrators (FANUC, Cognex, etc) who are focused on factory automation.

Domanda 1
What are fundamental, essential, and homography matrices and how are they different from each other? What are the components of a camera intrinsics matrix? How do you correct for lens distortion? What are the units of the elements in the camera intrinsics matrix? What happens to the camera intrinsics after you crop an image? How do you convert from 3D world coordinates to 2D mage coordinates?
Ask about the fundamental conceptual ideas of computer vision, like transpose matrix, and 3d reconstruction. And give a specific question, ask what is the process of getting the pose of the item.
