Applied through job portal, and had a 1-hour phone call interview for signal/audio processing area. Had basic questions on DSP like upsampling, downsampling, etc and coding based questions like complexity analysis .
First interview with algorithmic questions. He asked questions related to my project, but with a twist. I was very close on my answers but they didn't continue the process with me. Interviewer was very nice and patient
