very good questions and very interesting company, I ended up signed in another place so I didn't proceed but the place from the first interview look like one with very big potential
Interview questions [1]
Question 1
to implement two threads which communicate by queue between them with self queue implementation (cyclic buffer)
I applied through a recruiter. I interviewed at Xsight Systems (Rosh Ha`Ayin) in Jan 2021
Interview
Started with an interview on phone that lasted about 20 mins, mainly talking about what kind of work I did previously.
Next stage was a white board interview. The questions were not so tough, the interviewer mainly wanted to see if you are very fluent with the backend langueges they use, although he didnt say it was one of the top things he was looking for, that was the feeling he gave.
Next step was a home test to build a single page application. The description was very vague and it wasn't very clear what to emphasize in the solution.
