I applied through a recruiter. The process took 1 day. I interviewed at Vitrociset (Rome) in Apr 2016
Interview
The interview took place in a room with 3 employees (2 engineers + 1 hr).
They are really interested in your knowledge about major methodologies employed in modern technology (like Kalman filters, Neural Networks, Vision algorithms...) and your background on algorithms and data structures. They ask about sorting algorithms, atomic operations for DB management, complexity (space/time), general knowledge about Linux systems...
Interview questions [1]
Question 1
How could you estimate the trajectory of a missile from 3 radar?
