Velmeni Deep Learning Engineer, Computer Vision interview questions

It is a startup that cannot even be searched on Crunchbase. This interviewer SKIPPED all the introductions and did not let me introduce myself. He has extremely poor communication skills. Seems like he completely doesn't know how to interview. Stupidly easy deep learning question, but in a vague way that misleads me. Besides, he is very unpolite. And it (Velmini) is still recruiting at LinkedIn. If you see that, don't waste your time applying.
