I talked to the recruiter first, who explained the entire process. Then came the system design interview. The interview went well.

I got an email a couple of days later stating that the interview went very well.

Next was the hiring manager. There were the usual questions, and he seemed very happy. He mentioned that he would ask the recruiter to arrange the next interview right away.

There was no email for the next few days, so I thought I would check with the recruiter. I got a two-line response that she would check with the hiring manager and let me know. I never heard again.

Typical System Design question with network diagram/APIs.
