First phone interview was with HR. a couple days later had another phone screen from an engineer. When I went in for the full day I Had four back to back interviews. One of the interviews was with two people. Mostly technical and finance questions. Seemed like a good place to work. No offer.

I had a phone screen with the lead technical recruiter. He had a very thick Russian-sounding accent and mumbled a lot, making it very difficult to understand him. I had to politely ask him to repeat himself numerous times and he responded by getting agitated. I don't understand why you would hire someone whose first language is not English to be the initial representative for your company. Not surprisingly, I didn't get another interview.
