Inform the interns after the interview.

According to my experience in interviewing Internet companies, as you said, it was the general manager of our company who interviewed me at that time. I didn't know he was the general manager at that time. As usual, he asked me a lot of trivial things and talked extensively. Later, he gave me his business card and asked me to contact him. A few days later, I had another interview with the head of my department, and it felt good, and I had to wait for the notice. As a result, I reported to the company in a few days.

Haha, so you don't have to worry. Basically, you will succeed, but you should also be prepared to find other jobs, which are more competitive than your current employment.

I hope it works for you.
