Everly Health Software Engineer interview questions

Phone screen with a recruiter followed by a phone screen with the CTO, followed by an in person interview with multiple people on the team in 3 separate meetings: one with more junior members of the team (engineering and QA), one with a product manager and an engineer, and the last with the CTO. In the interviews with two people, they asked questions across one another in a way that is confusing (one non-technical, then jumping into a technical question, back and forth). They sent along a technical challenge (~3-4hrs), but they didn't review it or ask about it.

I had a rather unpleasant phone interview experience with Everlywell. I applied via Indeed and got a response quickly. The interviewer was pleasant, but he asked me if I was married and if I had children. Since I am female, and these questions can be used as discrimination against women, I felt rather uncomfortable. (Goes against EEOC) Additionally, the interviewer asked me over the phone if I would come in the following week for an in-person interview. Then, the week later, they rescinded the offer to come in. All job hunters are rejected at some point and I don't take that personally, but I found it rather odd that they'd specifically tell me during a phone interview that they want me to come in for an in-person interview, keep me waiting, and then change their mind for no apparent reason.
