This interview was just... weird. There's no other word for it. The HR representative asked questions that didn't make sense with my level of experience, as if they were trying to downplay my experience. She also said that my compensation would be directly tied to the score I got on two assessments. So if you're a good timed test taker, they might use it to try to use it as an excuse to lower your salary. If you're a bad timed test taker, you're hosed.
They also wanted to know about my experience with SaaS companies and went through each company on my resume to see if it was actually SaaS. I get having industry experience (and I've only worked for SaaS companies), but I get the sense that they're not used to working with engineers or get what they do. For a tech company, they really don't understand tech workers...
HR talks a good game about their culture, but buyers beware. Do yourself a favor: READ THE REVIEWS FOR THIS COMPANY. Apparently, the CEO is a Grant Cardon proponent (ick) and the company invades their employees' privacy. Either trust people to be remote, or don't do it. I think that says everything you need to know about their culture...
