The process is okay. They reach out quickly and scheduled an onsite. The job posting online showed they are in SF but when I actually see the onsite address it showed Santa Clara. The job description online is very general and it would sound like you may work on different projects in the OEM company. While from the interview, you would only be working on a very specific component. From some points, the process is not professional enough. Such as they asked the interviewer to print the NDA themselves and bring it, which they could have done it easily on their own and gave it on site. From the interview, I think my expectation on salary (I think is average in Bay area ) is higher than theirs.

There are many behavior questions. The interviewer asked previous experiences. Also ask lots of questions about immigration status. Seems like she does not know too much about it. No move forward. Ghosted afterward.
