NXP Semiconductors DSP/Wlan developer interview questions

It was a very positive experience. There were 3 interviewers. who asked questions related to estimation detection, signal processing basics, probability, and other logical questions. Wasn't expecting numerical-based questions. hence the interview was a bit hard but overall very helping interviewers. Estimation detection: ml receiver question, dsp: interpolation and decimation question probability: what is the probability for two or more people to share a birthday in a room of 365 people?
