Image Sensing Systems Senior Algorithm Engineer interview questions

The hiring manager was unavailable at the time of my interview. I was then interview by several employees who would be at for the most part a lower level than the position I was interviewing for. This gave me a slightly different opportunity to check out the company. But, their infrastructure and technology was not at a high level, i.e. old not updated office and limited computer resources. In the end, we were not even close on salary expectation, so they did not make an offer, i.e. I told them I would reject their highest number.
