Hibu Senior Software Engineer interview questions

I learned of hibu through a recruiter. He gave the lowdown on what the company was, what the job was, and told me a bit about the hiring manager. After my resume was submitted (through the recruiter) I had a 30-minute phone screen where I chatted pretty casually with the hiring manager about my experience, what technologies the team works with, etc., and ended up scheduling an in-person interview. There was a second position for which I'd also phone-screened in similar fashion, so we had interviews lined up for both positions in a 4-hour block. I met with each hiring manager, then two pairs of each manager's employees, who mostly peppered me with technical questions. One of the hiring managers asked me to code on a whiteboard, and one set of his employees similarly asked me to code on paper.
