Initially, I applied online for the position and, after five weeks, received a request for a phone technical interview. I got the response after a few days (3-4 days) and was invited to an on-site interview.

The on-site interview was from 10 AM to around 4:30 PM. In total, I interviewed with eight people, including the HR person. All interviews, except for the lunch interview and the HR one, were technical and required problem-solving and coding on a whiteboard (in C).

The questions ranged from simple algorithms to debugging features and included fields that were not listed on my resume. At that time, I already had an offer from a different company, so I asked them for a quick response, which was negative with no additional explanation.

Write an implementation of malloc in C (referring to the stack and heap).

Describe and write an implementation of a memcpy function, and suggest improvements (SSE copying using assembly and the 128-bit register).
