Is it cool to interview Amazon for a day without calling?

Small companies generally respond faster, because recruitment is also urgent. Some work in big companies is slow, so you need to wait patiently for a few days.

After the interview, take the initiative to ask the interviewer and let me know the time at the latest. If it takes more than a week, you can try to call the recruiter after the third day of the interview and ask him if he is satisfied. I really hope to join this company, not too direct.
