SDET opportunity

I have more than 8 years experience as SDET and was recently laid off as the company was not doing well and they had to.

I got a few calls and went to the final round for three positions. For some reason, I could not succeed as I see everyone being too picky these days to do an exact match. It was not the case a few years ago.

I appreciate if anyone could provide me with some resources for mock interviews and feedback.
