I applied through a recruiter. The process took 3 weeks. I interviewed at Espressif in May 2022
Interview
Very open and friendly team and HR. Participants at the meeting were involved and genuinely interested. The team leader was interested in my overall personality rather then checking the particular knowledge.

I applied online. The process took 4 weeks. I interviewed at Espressif (Shanghai, Shanghai) in Jul 2019
Interview
It was a very objective hiring process, I received contact from HR which made me a couple of questions regarding my experience and position expectations.
On the second round a F2F interview with HR where we entered deeper in my background details. One week after I attended the third round, with department manager, here was a technical round plus some comments of my previous projects.
After two weeks I got invited to final round with one of directors, again a technical talk plus some comments of my expectations and details of the role.
I got an offer from they and accepted after two weeks of last round, the interviewers are very nice people, they really put effort to make the interviews enjoyable for both sides.
