Basic algorithms, stochastic, probability questions are included in. As well as some research topics.
Most of the interviewers are very nice. One of them is kind of rude and impatient. Stop you when you just saying three sentences about the introduction.
I applied online. I interviewed at Fujitsu (Sunnyvale, CA)
Interview
The interview went well.
I got an offer a few days later. The offer was way lower than market. I sent them some numbers more aligned to what a person with my experience is offered everywhere else.
After two weeks they answered they would not move forward, CANCELLING THE ORIGINAL OFFER. This is probably the most unprofessional process I have ever faced.
