The process took 6 weeks. I interviewed at Zoom Communications in Jul 2021
Interview
All interview take about 1.5 months, and there are three interviews in total. One background interview, one coding (leetcode) + system design interview, and one behavior interview.
Overall, HR treats me nice, and interviewr are professional.

Interview
I am quite confusing.
I have not received any interview invitation yet.
I am not sure this is the technical mistake or the usual way of the hiring procedure.
Am I suppose to have an interview or not ?
There are three interview stages, including two technical stages and one behavior stage (optional).
The recruiter will kindly help you through the entire interview process.
The results of each stage are out real quick, which speeds up the whole progress.
It's an excellent interview experience.
