First HR interview was coherent, however after this HR interview the technical interview took part. Around 40 minutes, one of the interviewer asked only one topic: Convolution layer and difference with a standard nn layer. The interviewer has some structured answers in his mind and until I got them, he neither tried a way to explain differently nor changed the question. + he had a confusion in his mind about Equivariance in cnns. Later coding question arrived. This part was coherent.
